Towers of Function Fields over Non-prime Finite Fields

Algebraic Geometry 2013-05-21 v2 Number Theory

Abstract

Over all non-prime finite fields, we construct some recursive towers of function fields with many rational places. Thus we obtain a substantial improvement on all known lower bounds for Ihara's quantity A()A(\ell), for =pn\ell = p^n with pp prime and n>3n>3 odd. We relate the explicit equations to Drinfeld modular varieties.
