Bertini’s theorem for F-rationality (Austyn Simpson, Bates College)
A classical principle in algebraic geometry is that a general hyperplane section of a variety should have singularities no worse than those of the variety itself. Over the complex numbers, this principle is known to hold for rational singularities. Rational singularities are related via reduction mod p to a notion called F-rationality, which is defined […]

CCMS Colloquium: Frobenius invariants — Austyn Simpson (Bates College)
Abstract: Rings containing a finite field mathbb{F}_p (such as the ring of polynomials with coefficients in mathbb{F}_p) admit a map called the Frobenius homomorphism which sends every element to its p-th power. This operation encodes delicate information about the geometry of the zero sets of polynomial equations in prime characteristic, such as whether they are […]
