Freeness Conditions of Tensors and Coproducts of Groups

Department of Mathematics, Faculty of Science and Arts, University of Celal Bayar, Muradiye Campus 45035 Manisa, Turkey

Abstract

Using a free simphicial group with given a CW-basis, we give an alternative description of the top group of the free square complex and 2-crossed complex of groups on 2-construction data in terms of tensors and coproducts of crossed module of groups. Therefore the functors are given between these categorical constructions.
