Description:
Title: Applications of Frobenius to characteristic zero
Abstract: For nearly forty years, mathematicians have used the Frobenius morphism, or p-th power map, to investigate phenomena in algebraic geometry, representation theory, number theory, and commutative algebra. Remarkably, though Frobenius only makes sense in prime characteristic, some of its most interesting applications occur in the context of characteristic zero! In this talk, we will discuss some of these applications, with an eye towards classical singularity theory , and birational algebraic geometry, both over the complex numbers.
