Abstract

In this paper, we give a necessary and sufficient condition for a generalized real Bott manifold to have a spin structure in terms of column vectors of the associated matrix. We also give an interpretation of this result to the associated acyclic ω-weighted digraphs. Using this, we obtain a family of real Bott manifolds that does not admit spin structure
