On Bott-Chern and Aeppli cohomologies of two-dimensional toroidal groups

A toroidal group is a generalization of a complex torus, and is obtained as the quotient of the complex Euclidean space ${\mathbb{C}}^n$ by a discrete subgroup. Toroidal groups with finite-dimensional cohomology, called theta toroidal groups, are known to exhibit behavior analogous to that of complex tori. We compute Bott–Chern and Aeppli cohomologies for two-dimensional non-compact theta toroidal groups.
