Abstract

Given a tropical variety X and two non-negative integers p and q we define a homology group \(H_{p,q}(X)\) which is a finite-dimensional vector space over \({\mathbb {Q}}\). 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 \(\dim H_{p,q}(X)\) coincides with the Hodge number \(h^{p,q}\) of a general member of the family.
