Singularities: characteristic zero vs. positive characteristic
Abstract: In characteristic zero, one can define invariants of singularities
via valuations, or equivalently, via resolutions of singularities. In
positive characteristic, invariants can be defined in a very elementary way,
using
the Frobenius homomorphism. This talk will be about analogies and
connections between these two points of view (with focus on positive
characteristic).
