Abstract

In this article, we associate new invariants called pseudo-homology and pseudo-cohomology groups to right quasigroups and in turn to geometric spaces with natural quasigroup structures and to general extensions. It initiates a program to differentiate different types of general extensions.

Keywords

general extension; $c$-groupoid; right quasigroup; pseudo-cohomology
