Abstract

In this short article we give a geometric meaning of the divisibility of KOKO-theoretical Euler classes for given two spin modules. We are motivated by Furuta's 10/8-inequality for a closed spin 44-manifold. The role of the reducibles is clarified in the monopole equations of Seiberg-Witten theory, as done by Donaldson and Taubes in Yang-Mills theory.
