Braided strict Ann-categories and commutative extensions of rings
Abstract
A braided E-system is a version of braided crossed module for rings. In this paper we present applications of the braided Ann-category theory to the problem of classifications of braided E-systems, of ring extensions of the type of a strong braided E-system, and of extensions of commutative rings.
