Surjectivity of cycle maps for singular varieties

Algebraic Geometry 2015-07-17 v1

Abstract

A theorem of Jannsen asserts that if a smooth projective variety has injective cycle class maps, it has surjective cycle class maps. The object of this note is to present a version of Jannsen's theorem for singular quasi--projective varieties.
