SUMMARY:Characterizing every finitely generated field by a field axiom
DESCRIPTION:Oberseminar Algebra und Geometrie \nFlorian Pop (University of Pennsylvania\, Philadelphia) \nAbstract:\nRecall that the Hilbert Problem 10 (HP10) has a negative answer (by work of Davis\, Putman\, Julia Robinson\, culminating with Matijasevich). That implies at least intuitively that the arithmetic of global fields is “very complicated.” An intriguing question arising from the negative solution to HP10 is whether the arithmetic is so complicated that the isomorphism type of every global field can be “encoded” in a single field axiom\, i.e.\, whether for every global field $K$ there is a field axiom\, say $\varphi_K$\, such that for all global fields $L$ one has $L\cong K$\, provided $\varphi_K$ is true in $L$. It was shown by Rumely in 1980 that such a field axiom $\varphi_K$ does exist indeed for every global field $K$. In my talk I will explain all the terms\, and show that the above fact is true for  all finitely generated fields. This is joint work with Philip Dittmann.

SUMMARY:The Gauss problem for central leaves
DESCRIPTION:Valentijn Karemaker (Universiteit Utrecht) \nAbstract: \nFor a family of finite sets whose cardinalities are naturally called class numbers\, \nthe Gauss problem asks to determine the subfamily in which every member has class number one. \nWe study the Siegel moduli space of abelian varieties in characteristic p and solve the Gauss problem \nfor the family of central leaves\, which are the loci consisting of points whose associated p-divisible groups \nare isomorphic. Our solution involves mass formulae\, computations of automorphism groups\, \nand a careful analysis of Ekedahl-Oort strata in genus 4. This geometric Gauss problem is \nclosely related to an arithmetic Gauss problem for genera of positive-definite quaternion Hermitian lattices\, \nwhich we also solve.\nOberseminar Algebra und Geometrie (Frankfurt)
