Title: Vector fields on canonically polarized surfaces Abstract: In this talk I will present some results about the geometry of canonically polarized surfaces defined over a field of positive characteristic which have a nontrivial global vector field, equivalently non reduced automorphism scheme, and the implications that the existence of such surfaces has in the moduli problem of canonically polarized surfaces.

Title: Frobenius numbers. Abstract: For a natural number $k$, the $k$-th (generalised) Frobenius number of relatively prime natural numbers $(a_1, \dots, a_n)$ is the largest natural number that cannot be written as a non-negative integral combination of $(a_1, \dots, a_n)$ in $k$ distinct ways. We study the $k$-th Frobenius number from a commutative algebraic perspective. We interpret the $k$-th Frobenius number in terms of the Castelnuovo-Mumford regularity of certain modules associated to $(a_1, \dots, a_n)$. We study these modules in detail and using this study, show that the sequence of generalised Frobenius numbers form a finite difference progression, i.e. a sequence whose set of successive differences form a finite set. This talk is based on a joint work with Ben Smith.
