A Weak (k,k)-Lefschetz Theorem for Projective Toric Orbifolds

Algebraic Geometry 2023-02-09 v1

Abstract

Firstly we show a generalization of the (1,1)-Lefschetz theorem for projective toric orbifolds and secondly we prove that on 2k-dimensional quasi-smooth hypersurfaces coming from quasi-smooth intersection surfaces, under the Cayley trick, every rational (k,k)-cohomology class is algebraic, i.e., the Hodge conjecture holds on them.
