Cohomological classication of Ann-categories
Abstract
An Ann-category is a categorication of rings. Regular Ann-categories were
classied by Shukla cohomology of algebras. In this paper, we state and prove the precise theorem on classication of Ann-categories in the general case based on Mac Lane cohomology of rings.
