Abstract

This paper is about a generalization of famous Inoue's surfaces. Let MM be a matrix in SL(2n+1,Z)SL(2n+1,\mathbb{Z}) having only one real eigenvalue which is simple. We associate to MM a complex manifold TMT_M of complex dimension n+1n+1. This manifold fibers over S1S^1 with the fiber T2n+1\mathbb{T}^{2n+1} and monodromy MM^\top. Our construction is elementary and does not use algebraic number theory. We show that some of the Oeljeklaus-Toma manifolds are biholomorphic to the manifolds of type TMT_M. We prove that if MM is not diagonalizable, then TMT_M does not admit a K\"ahler structure and is not homeomorphic to any of Oeljeklaus-Toma manifolds.
