Abstract: We introduce the notion of an induced 2-crossed module, which extends the notion of an induced crossed module (Brown and Higgins).

Abstract: We study the notion of internal crossed module in terms of cross-effects of the identity functor. These cross-effects give rise to a concept of commutator which allows a description of inter...

In this paper, we define the notion of pseudo 2-crossed module and give a relation between the pseudo 2-crossed modules and pseudo simplicial groups with Moore complex of length 2.

In this paper we first review the definitions of crossed module [10], pullback crossed module and cat1-object in the category of commutative algebras. We then describe a certain pullback of cat1- comm...

In this paper, we presented a brief review of crossed modules [7], cat1-groups [6], pullback crossed modules [4], pullback cat1-group [1], profinite crossed modules [5], cat1-profinite groups [5], pul...

In this paper, wer define the pullback cat1-groups and we showed that the category of bullback cat1-group is equivalent to the category of pullback crossed modules. 1991 A. M. S. C.: 13D99, 16A99, 17B...
