DESCRIPTION:Jakub Witaszek (University of Michigan)\nWhat allowed for many
  developments in algebraic geometry and commutative algebra was a discover
 y of the notion of a Frobenius splitting\, which\, briefly speaking\, dete
 cts how pathological positive characteristic Fano and Calabi-Yau varieties
  can be. Recently\, Yobuko introduced a more general concept\, a quasi-F-s
 plitting\, which captures much more refined arithmetic invariants. In my t
 alk\, I will discuss on-going projects in which we develop the theory of q
 uasi-F-splittings in the context of birational geometry and derive applica
 tions\, for example\, to liftability of singularities. This is joint work 
 with Tatsuro Kawakami\, Hiromu Tanaka\, Teppei Takamatsu\, Fuetaro Yobuko\
 , and Shou Yoshikawa.
