  •  P.D. rings with a view towards Crystals
  •  09/16/2019
  •  4:30 PM - 5:30 PM
  •  C304 Wells Hall

In this talk we will define P.D. rings, which are triples consisting a ring, an ideal of the ring and a map on an ideal mimicking $x^n/n!$. We will give some examples of P.D. rings and discuss their properties. Then we will use the P.D. structures to define the crystalline site of schemes and crystals. If time admits we will talk about some examples of crystals and explain why we care about them.
