Relations between some invariants of algebraic varieties in positive characteristic

Gerard van der Geer, Toshiyuki Katsura

We discuss relations between certain invariants of varieties in positive characteristic, like the a-number and the height of the Artin-Mazur formal group. We calculate the a-number…

Generators for modules of vector-valued Picard modular forms

Fabien Cléry, Gerard van der Geer

We construct generators for modules of vector-valued Picard modular forms on a unitary group of type (2,1) over the Eisenstein integers. We also calculate eigenvalues of Hecke oper…
