Abstract

Given a tropical variety X and two non-negative integers p and q we define a homology group Hp,q(X) which is a finite-dimensional vector space over Q. We show that if X is a smooth tropical variety that can be represented as the tropical limit of a 1-parameter family of complex projective varieties, then dim Hp,q(X) coincides with the Hodge number hp,q of a general member of the family.
