DESCRIPTION:Title: <a href="https://researchseminars.org/talk/cazoom/2/">L
 ocal Cohomology of Thickenings on Sequences of Rings</a>\nby Jenny Kenkel 
 (University of Kentucky) as part of CAZoom\n\n\nAbstract\nLet $R$ be a sta
 ndard graded polynomial ring and let $I$ be a homogenous prime ideal of \n
 $R$. Bhatt\, Blickle\, Lyubeznik\, Singh\, and Zhang examined the local co
 homology of $R/I^t$\nas $t$ grows arbitrarily large. I will discuss their 
 results and give an explicit description of the transition maps between th
 ese local cohomology modules in a particular example. I will also consider
  asymptotic structure in a different direction: as the number of variables
  of \n$R$  grows. This study of families of modules over compatible varyin
 g rings hints at the existence of FI structures.\n
