DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VCAS/121/">K
 odaira vanishing for thickenings of globally $F$-regular varieties</a>\nby
  Shunsuke Takagi (University of Tokyo) as part of IIT Bombay Virtual Commu
 tative Algebra Seminar\n\n\nAbstract\nBlickle-Bhatt-Lyubeznik-Singh-Zhang 
 proved that if $X$ is a projective variety over a field $k$ of characteris
 tic zero with isolated complete intersection singularities\, then the Koda
 ira vanishing theorem holds for all thickenings of $X$. What if $k$ is of 
 positive characteristic? Kodaira vanishing can fail in positive characteri
 stic\, but it still holds for Frobenius split varieties. In this talk\, I 
 will discuss Kodaira vanishing for thickenings of globally $F$-regular var
 ieties\, a special class of Frobenius split varieties. This talk is based 
 on joint work with Kenta Sato.\n
