The title of this talk is borrowed from a seminal paper by Arveson discussing noncommutative analogues of the Hardy space H^∞(T) via the socalled subdiagonal algebras. Subdiagonal algebras are a family of nonselfadjoint operator algebras which give a common perspective to the study of some triangular operator algebras (for example, the algebra of block upper triangular matrices in M_n(C)), Dirichlet function algebras, etc. The first part of the talk will be about a noncommutative version of innerouter factorization in finite maximal subdiagonal algebras. We will then discuss a proof of a version of Jensen's inequality in this setting which relates to some classical results by Szegö.

 C517 Wells Hall
Bregmandivergence is a wellknown generalized distance framework in various applications, such as machine learning and image processing. In this talk, by using dual structure of the Bregmandivergence associated with the subclass of convex function of Legendre function, we analyze the structure of the Legendre exponential families whose cumulant function corresponds to the conjugate convex function of Legendre type. Actually, Legendre exponential families are the extended version of the regular exponential families to include nonregular exponential families, such as the inverse Gaussian distribution. The main advantage of the proposed Bregmandivergencebased approach is that it offers systematic successive approximation tools to handle closed domain issues arising in nonregular exponential families and the statistical distribution having discrete random variables, such as Bernoulli distribution and Poisson distribution. In addition, we also introduce the generalized centerbased clustering algorithm based on the Tweedie distribution.

A discrete analogue of the Dirichlet problem of the Aleksandrov theory of the MongeAmere equation is derived in this paper. The discrete solution is not required to be convex, but only discrete convex in the sense of Oberman. We prove that the uniform limit on compact subsets of discrete convex functions which are uniformly bounded and which interpolate the Dirichlet boundary data is a continuous convex function which satisfies the boundary condition strongly. The domain of the solution needs not be uniformly convex. We obtain the first proof of convergence of a wide stencil finite difference scheme to the Aleksandrov solution of the elliptic MongeAmpere equation when the right hand side is a sum of Dirac masses. The discrete scheme we analyze for the Dirichlet problem, when coupled with a discretization of the second boundary condition, as proposed by Benamou and Froese, can be used to get a good initial guess for geometric methods solving optimal transport between two measures.

Among the classical geometric evolution equations, YM flow is the least nonlinear and best behaved. Nevertheless, curvature concentration is a subtle problem when the base manifold has dimension four. I'll discuss my proof that finitetime singularities do not occur, and briefly describe the infinitetime picture.

Abstract: On the one hand, there is a 3d Calabi Yau category with stability conditions associated to a quiver without loops or 2cycles with generic potential, and one can study its DonaldsonThomas invariants. On the other hand, such a quiver also defines a cluster Poisson variety, which is constructed by gluing a collection of algebraic tori in a certain way governed by combinatorics. In certain cases, the DonaldsonThomas invariants of the former category can be captured by an automorphism on the latter space. In this talk, I will recall the cluster Poisson structure on the moduli space of configurations of points in a projective space, and state my result on constructing the corresponding cluster DonaldsonThomas transformation, and give a new proof of Zamolodchikov’s periodicity conjecture in the $A_m\boxtimes A_n$ cases as an application. If time permits, I will also talk about the generalization of this result to double Bruhat cells.

 C304 Wells Hall
In applications in computer graphics and computational anatomy, one seeks measurepreserving maps between shapes which preserve geometry as much as possible. Inspired by this, we define a distance between arbitrary compact metric measure spaces by blending the Monge formulation of optimal transport with the GromovHausdorff construction. We show that the resulting distance is an extended quasimetric on the space of compact mmspaces, which has convenient lower bounds defined in terms of distance distributions. We provide rigorous results on the effectiveness of these lower bounds when restricted to simple classes of mmspaces such as metric graphs or plane curves.This is joint work with Facundo Mémoli.

Abstract: Compatible subsets of edges in a maximal Dyck path were introduced by Lee, Li, and Zelevinsky as a tool for constructing nice bases for rank two cluster algebras. In this talk, I will present a generalization of this combinatorics and give two applications. The first application is a combinatorial construction of noncommutative rank two generalized cluster variables which proves a conjecture of Kontsevich. The second application gives a combinatorial description of the cells in an affine paving of rank two quiver Grassmannians, this part is joint work with Thorsten Weist.

 09/14/2018
 4:10 PM  5:00 PM
 1502 Engineering Building
In this talk, an entirely new class of highorder numerical algorithms for computational fluid dynamics is introduced. The new method is based on the Gaussian Processes (GP) modeling that generalizes the Gaussian probability distribution. The new approach is to adopt the idea of the GP prediction technique which utilizes the covariance kernel functions and use it to interpolate and/or reconstruct highorder approximations for computational fluid dynamics simulations. The new GP highorder method is proposed as a new numerical highorder formulation in finite difference and finite volume frameworks, alternative to the conventional polynomialbased approaches.

 C517 Wells Hall
The notion of an absolute value function can be generalized to arbitrary fields; one example is the padic absolute value on the rational. Ostrowski's theorem classifies all absolute values on the rationals. An absolute value induces a metric in a natural way, so we can "complete" a field with respect to a given absolute value. We'll also discuss the close relationship between absolute values and discrete valuation rings.

 4:10 PM  5:30 PM
 C304 Wells Hall
The question in title is akin to asking where the equation of motion of a free falling object a + bt + 1/2 gt^2 in 3space come from? then discovering that the "objects fall with constant acceleration" rule. Similarly, we derive SeibergWitten equations (which also have a linear part and a quadratic part) from the deformation equations of an "isotropic associative submanifold" of a complex G_2 Manifold. For this, we will define the notion of complex G_2 manifold and notion of complexification of a G_2 manifold (this is a joint work with Ustun Yildirim).

 C517 Wells Hall
Krein signature is an algebraic quantity characterizing purely imaginary eigenvalues of linearized Hamiltonian systems. Instabilities growing from a stable state in these systems are caused by HamiltonianHopf bifurcations, i.e. events when two purely imaginary eigenvalues collide and split off the imaginary axis. The necessary condition for such an event is that the colliding eigenvalues must have mixed signature. In the talk we present three elegant results related to Krein signature  graphical Krein signature and its use to simplify proofs, a connection to stability in general extended systems, and ability to characterize the nature of the eigenvalue collisions directly from the reduced dispersion relation.

 C117 Wells Hall
In 2014 it was conjectured that the equality of the cluster algebra and upper cluster algebra is equivalent to the existence of a maximal green sequence. In this talk we will discuss a stronger result for cluster algebras from mutationfinite quivers with an emphasis on surface cluster algebras. Specifically we show that for all quivers from surface cluster algebras there exists a maximal green sequence if and only if the cluster algebra is equal to the cluster algebra if and only if the cluster algebra is locallyacyclic. We will also provide a counterexample to show that the result does not hold in general.

 C304 Wells Hall
An {\em ordered set partition} of size $n$ is a set partition of $\{1, 2, \dots, n \}$ with a specified order on its blocks. When the number of blocks equals the number of letters $n$, an ordered set partition is just a permutation in the symmetric group $S_n$. We will discuss some combinatorial, algebraic, and geometric aspects of permutations (due to MacMahon, Carlitz, Chevalley, Steinberg, Artin, LusztigStanley, Ehresmann, Borel, and LascouxSch\"utzenberger). We will then describe how these results generalize to ordered set partitions and discuss a connection with the HaglundRemmelWilson {\em Delta Conjecture} in the field of Macdonald polynomials. Joint with Jim Haglund, Brendan Pawlowski, and Mark Shimozono.

 C304 Wells Hall
Hitchin singled out a preferred component in the character variety of representations from the fundamental group of a surface to PSL(d,R). When d=2, this Hitchin component coincides with the Teichm\"uller space consisting of all hyperbolic metrics on the surface. Later Labourie showed that Hitchin representations share many important differential geometric and dynamical properties.
Parreau extended previous work of Thurston and MorganShalen to a compactification of the Hitchin component whose boundary points are described by actions of the fundamental group of the surface on a building.
In this talk, we offer a new point of view for the Parreau compactification, which is based on certain positivity properties discovered by Fock and Goncharov. Specifically, we use the FockGoncharov construction to describe the intersection patterns of apartments in invariant subsets of the building that arises in the boundary of the Hitchin component.

Topological quantum field theories (TQFTs), inspired by theoretical physics, produce manifold invariants behaving well under gluing. For every discrete group G, homotopy quantum field theories (HQFTs) are Gequivariant versions of TQFTs. In this talk we define and classify 2dimensional extended HQFTs by generalizing methods introduced for TQFTs by Chris SchommerPries in 2009. We list generators and relations for the extended Gequivariant bordism bicategory and use them to classify 2dimensional extended HQFTs.

In 19481950, V.Ya.Kozlov (19142007) stated a series of
interesting geometric properties of dilated systems D(f)= {f(kx): k=

In particular, for a RademacherHaarWalsh type generator f=
2periodic odd extension of the indicator function of (0,a), 0<a<1,
the system D(f) was claimed to be complete/incomplete for many
particular values of a. We prove all Kozlov's statements and several
new, as well as discuss other geometric properties of D(f).

 C517 Wells Hall
We study various Banach spaces of holomorphic functions on the unit
disc and half plane. As a main question we investigate the boundedness
of the corresponding holomorphic projection. We exploit the idea of
V.P.Zaharyuta, V.I.Yudovich (1962) where the boundedness of the
Bergman projection in Lebesgue spaces was proved using
CalderonZygmund operators. We treat the cases of variable exponent
Lebesgue space, Orlicz space, Grand Lebesgue space and variable
exponent generalized Morrey space. The major idea is to show that the
approach can be applied to a wide range of function spaces. This opens
a door in a sense for introducing and studying new function spaces of
Bergman type in complex analysis. We also study the rate of growth of
functions near the boundary in spaces under consideration and their
approximation by mollifying dilations.
