Abstract

A toroidal group is a generalization of a complex torus, and is obtained as the quotient of the complex Euclidean space Cn\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.
