Title: Arithmetic of function fields
Date and place: June 13 (Monday), 4:00-5:00pm, mcm 610
Abstract: We explain an explicit construction and classification of all
Z_p-towers of a global function field of characteristic p > 0, via Witt
vectors.In particular, we will give an explicit genus formula for any
such Z_p tower and classify those towers whose genus sequence is
stable. This is joint work with Michiel Kosters.
