For a complex torus X=V/Λ of complex dimension g, constant forms give a natural isomorphism H∂ˉp,q​(X)≅⋀pV∗⊗⋀qV∗. A flat Kähler metric and the Dolbeault Hodge decomposition prove that these constant forms are precisely the harmonic representatives. Thus hp,q=(pg​)(qg​) for 0≤p,q≤g, and zero otherwise.
