The Hodge number h^1,1 of irregular algebraic surfaces

Algebraic Geometry 2014-02-27 v1

Abstract

We prove a new inequality for the Hodge number h^1,1 of irregular complex smooth projective surfaces of general type without irregular pencils of genus >1. More specifically we show that if the irregularity q satisfies q=2^k+1 then h^1,1>4q-4.
