Authors: MURAT ALP

Abstract: In this paper we first review the definitions of crossed module [10], pullback crossed module and cat^1-object in the category of commutative algebras. We then describe a certain pullback of cat^1- commutative algebras.

Keywords: Crossed modules, Cat^1-Algebra, Pullback, Commutative Algebra
