 C304 Wells Hall
Most closed 4manifolds do not admit symplectic forms, but most admit "nearsymplectic forms", certain closed 2forms which are symplectic outside of a collection of circles. This provides a gateway from the symplectic world to the nonsymplectic world. I will first briefly sketch a geometric interpretation of the SeibergWitten invariants in terms of Jholomorphic curves that are compatible with the nearsymplectic form. Although the SeibergWitten invariants don't apply to (potentially exotic) 4spheres, nor do these spheres admit nearsymplectic forms, there is still a way to bring in nearsymplectic techniques.

 C304 Wells Hall
The theory of qanalogues is important in both combinatorics and the study of hypergeometric series. Roughly speaking, the qanalogue of a mathematical object (which could be a number or a theorem or ...) is another object depending on a parameter q which reduces to the original object when q=1. This talk will be a gentle introduction to qanalogues. No background will be assumed.

 C304 Wells Hall
A oneparameter unitaryvalued interpolation between any two unitary matrices (e.g., quantum gates) is constructed based on the Cayley transformation. We prove that this path induces probability measures that are arbitrarily close to the Haar measure and prove the simplest known averagecase # P hardness of random circuit sampling (RCS). RCS is the task of sampling from the output distribution of a quantum circuit whose local gates are random Haar unitaries, and is the lead candidate for demonstrating quantum supremacy in the "noisy intermediate scale quantum (NISQ)" computing era. Here we also prove exp(Θ(n^4 )) robustness with respect to additive error. This overcomes issues that arise for extrapolations based on the truncations of the power series representation of the exponential function. (Dis)Proving the quantum supremacy conjecture requires an extension of this analysis to noise that is polynomially small in the system's size. This remains an open problem. Lastly, an efficient and private protocol for blind quantum computation is proposed that uses the Cayley deformations proposed herein for encryption. This is an efficient protocol that only requires classical communication between Alice and Bob.
** The talk is selfcontained and does not require any prereq beyond basic linear algebra (e.g, knowing what a unitary matrix is).

I'll discuss a forthcoming paper studying families of $G_2$instantons on $S^7$, focusing on those which are obtained by pulling back asd instantons on $S^4 $ via the quaternionic Hopf fibration. In the charge1 case this yields a smooth and complete 15dimensional family. The situation for higher charge is more complicated, but we are able to compute all the infinitesimal deformations.

The fundamental premise of statistical mechanics is that a physical system's state is random according to some probability measure, which is determined by the various forces of interaction between the system's constituent particles. In the ``disordered" setting, these interactions are also random (meant to capture the effect of a random medium), meaning the probability measure is itself a random object. This setting includes several of the models most widely studied by mathematical physicists, such as the Random Energy Model, the SherringtonKirkpatrick spin glass, and directed polymers. The most intriguing part of their phase diagrams occurs at low temperature, when the measure concentrates, or "freezes", on energetically favorable states. In general, quantifying this phenomenon is especially challenging, in large part due to the extra layer of randomness created by the disorder. This talk will describe recent progress on this question, leading us to some conjectures on further open problems. (Joint work with Sourav Chatterjee)

 Gröbner basis and the Ideal Membership problem
 09/09/2019
 4:30 PM  5:30 PM
 C304 Wells Hall
We know from the Hilbert Basis Theorem that any ideal in a polynomial ring over a field is finitely generated. However, there remains question as to the best generators to choose to describe the ideal. Are there generators for a polynomial ideal $I$ that make it easy to see if a given polynomial $f$ belongs to $I$? For instance, does $2x^2z^2+2xyz^2+2xz^3+z^31$ belong to $I=(x+y+z, xy+xz+yz, xyz−1)$? Deciding if a polynomial is in an ideal is called the Ideal Membership Problem. In polynomial rings of one variable, we use long division of polynomials to solve this problem. There is a corresponding algorithm for $K[x_1,\ldots, x_n]$, but because there are multiple variables and multiple divisors, the remainder of the division is not unique. Hence a remainder of $0$ is a sufficient condition, but not a necessary condition, to determine ideal membership. However, if we choose the correct divisors, then the remainder is unique regardless of the order of the divisors. These divisors are called a Gröbner basis. In our talk we will define the Gröbner basis and see how it solves the Ideal Membership Problem.

 C304 Wells Hall
The Lucas sequence is a sequence of polynomials in $s,t$ defined recursively by $\{0\}=0$, $\{1\}=1$, and $\{n\}=s\{n1\}+t\{n2\}$ for $n\ge2$. On specialization of $s$ and $t$ one can recover the Fibonacci numbers, the nonnegative integers, and the $q$integers $[n]_q$. Given a quantity which is expressed in terms of products and quotients of nonnegative integers, one obtains a Lucas analogue by replacing each factor of $n$ in the expression with $\{n\}$. It is then natural to ask if the resulting rational function is actually a polynomial in $s$ and $t$ and, if so, what it counts. Using lattice paths, we give combinatorial models for Lucas analogues of binomial coefficients. We also consider Catalan numbers and their relatives, such as those for finite Coxeter groups. This is joint work with Curtis Bennett, Juan Carrillo, and John Machacek.

 Rough solutions to the threedimensional compressible Euler equations with vorticity and entropy
 09/11/2019
 4:10 PM  5:00 PM
 C304 Wells Hall
We prove a series of intimately related results tied to the regularity and geometry of solutions to the threedimensional compressible Euler equations.
The solutions are allowed to have nontrivial vorticity and entropy, and an arbitrary equation of state with positive sound speed. The central theme is that under low regularity assumptions on the initial data, it is possible to avoid, at least for short times, the formation of shocks. Our main result is that the time of classical existence can be controlled under low regularity assumptions on the part of the initial data associated with propagation of sound waves in the fluid. Such low regularity assumptions are in fact optimal. To implement our approach, we derive several results of independent interest: (i) sharp estimates for the acoustic geometry, which in particular capture how the vorticity and entropy interact with the sound waves; (ii) Strichartz estimates for quasilinear sound waves coupled to vorticity and entropy; (iii) Schauder estimates for the transportdivcurlpart of the systems. Compared to previous works on low regularity, the main new feature of our result is that the quasilinear PDE system under study exhibit multiple speeds of propagation. In fact, this is the first result of its kind for a system with multiple characteristic speeds. An interesting feature of our proof is the use of techniques that originated in the study of the vacuum Einstein equations in general relativity.

 C304 Wells Hall
We study two different invariants of framed oriented links. Augmentations are rank one representations of a noncommutative algebra, whose definition is motivated by Floer homology. Sheaves in microlocal theory can be thought of as generalizations of link group representations. We will demonstrate two constructions going back and forth between these invariants. We will also tell a motivating story behind the scene, using SFT and microlocalization correspondence in symplectic topology.

 Developing Finite Element Solvers for Poroelasticity in the Twofield Approach
 09/13/2019
 4:10 PM  5:00 PM
 C304 Wells Hall
This talk presents results from our recent efforts for reviving the 2field approach (fluid pressure and solid displacement) for numerically solving poroelasticity problems. We choose quadrilateral and hexahedral meshes for spatial discretization since they are equally flexible in accommodating complicated domain geometry but involve less unknowns, compared to simplicial meshes. The Darcy equation is solved for fluid pressure by the novel weak Galerkin finite element methods, which establish the discrete weak gradient and numerical velocity in the ArbogastCorrea spaces. The elasticity equation is solved for solid displacement by the enriched Lagrangian elements, which were motivated by the BernardiRaugel elements for Stokes flow. These two types of finite elements are coupled through the implicit Euler temporal discretization to solve poroelasticity. Numerical experiments on benchmarks will be presented to show that the new solvers are lockingfree. Implementation on deal.II will be discussed also. This talk is based on a series of joint work with several collaborators.

 Perfectoid Fields and Tilting

 10:00 AM  11:30 AM
 C329 Wells Hall
In this talk we will introduce perfectoid fields and tilting. Perfectoid fields provide the the correct base scheme for perfectoid spaces. Tilting is a fundamental tool that will let us lift characteristic $0$ results to characteristic $p$ results. For example, if $K$ is a characteristic $0$ perfectoid field and $K^{\flat}$ is a tilt of $K$ then $K^{\flat}$ is a characteristic $p$ field; $K^{\circ}/K^{\circ\circ}\cong K^{\flat \circ}/K^{\flat\circ\circ}$; if $[L:K]$ is finite then $[L^{\flat}:K^{\flat}]=[L:K]$ (in particular, $L$ is perfectoid); and there is an equivalence of categories between finite étale covers of $K$ and finite étale covers of $K^{\flat}$ via $L\mapsto L^{\flat}$.
This talk will not require any material beyond firstyear graduate algebra. However, the sophistication required may be higher. To make this talk as accessible as possible, we will include numerous examples.

We will discuss the notion of tracial stability for operator algebras. Morally, an algebra A is tracially stable if approximate homomorphisms on A are near honest homomorphisms on A. We will discuss several examples and nonexamples of tracially stable algebras including certain graph products (simultaneous generalization of free and tensor products) of C*algebras. We will also discuss properties closely related to tracial stability that provide new characterizations of amenability.

 C304 Wells Hall
If one considers the set of mcomponent based links in R^3
with a 4dimensional equivalence relationship on it, called
concordance, one can form a group called the link concordance group,
C^m. Questions in concordance are important in for classification
questions in topological and smooth 4manifolds It is well known that
the link concordance group contains the isotopy class of pure braid
with m strands, P_m. That is, two braids are concordant if and only
if they are isotopic! In the late 90's Tim Cochran, Kent Orr, and
Peter Teichner defined a filtration of the knot/link concordance group
called the nsolvable filtration. This filtration gives a way to
approximate whether a link is trivial in the group. We discuss the
relationship between pure braids and the nsolvable filtration as well
as various other more geometrically defined filtrations coming from
gropes and Whitney towers. This is joint work with Aru Ray and Jung
Hwan Park.

In this talk we give an introduction to the analysis of the YangMills equation in higher dimensions. In particular, when studying sequences of solutions we will study the manner in which blow up can occur, and how this blow up may be understood through the classical notions of the defect measure and bubbles. The energy identity is an explicit conjectural relationship relating the energy density of the defect measure at a point to the bubbles which occur at that point. This talk is introductory and we will spend most of our time understanding the words of this abstract. If time permits we will briefly discuss the ideas needed to prove this conjecture and the related $W^{2,1}$conjecture. The work is joint with Daniele Valtorta.

Grothendieck's Theorem says that any vector bundle on $\mathbb{P}^1$ can be decomposed as a finite sum of line bundles. In this talk, we will discuss a generalization of this theorem: Horrocks Splitting Criterion. This criterion completely describes when a vector bundle on $\mathbb{P}^n$ splits as a sum of line bundles. We will then discuss an open conjecture of Hartshorne. If time permits, we will also consider the similar question of classifying when a vector bundle on $\mathbb{P}^n$ decompose as line bundles and twists of the tangent bundle.

 11:30 AM  12:30 PM
 C304 Wells Hall
In the context of 1D quantum spin chains, matrix product operators provide a way to study nonlocal operators such as translation in terms of quasilocal information. They have been used to describe a generalized form of symmetry for 1D systems on the boundary of 2D topological phases. In this talk, we will introduce some concepts of higher dimensional algebra, and a broad hypotheses about higher categories and spatially extended quantum systems. We will then explain how the collection of matrix product operators assembles into a higher (symmetric monoidal 2) category, and discuss some implications of this. Based on joint work with David Penneys.

We describe a scheme for constructing generating sets for Kronheimer and Mrowka's singular instanton knot homology for the case of knots in lens spaces. The scheme involves Heegaardsplitting a lens space containing a knot into two solid tori. One solid torus contains a portion of the knot consisting of an unknotted arc, as well as holonomy perturbations of the ChernSimons functional used to define the homology theory. The other solid torus contains the remainder of the knot. The Heegaard splitting yields a pair of Lagrangians in the traceless $SU(2)$character variety of the twicepunctured torus, and the intersection points of these Lagrangians comprise the generating set that we seek. We illustrate the scheme by constructing generating sets for several example knots. Our scheme is a direct generalization of a scheme introduced by Hedden, Herald, and Kirk for describing generating sets for knots in $S^3$ in terms of Lagrangian intersections in the traceless $SU(2)$character variety for the 2sphere with four punctures.

If time allows, I will describe some of the applications to classifying semisimple Lie algebras and reductive algebraic groups.
