Title: Spin-structures on real Bott manifolds with Kähler structures,
Abstract: Let M be a real Bott manifold with Kähler structure. Using Ishida
characterization we give necessary and sufficient condition for the existence
of the Spin-structure on M. In proof we use the technic developed in Popko,
Szczepański "Cohomological rigity of oriented Hantzsche-Wendt manifolds"
(Adv. Math. 302 (2016), 1044 - 1068) and characteristic classes.
