Some structural and closure properties of an extension of the q-tensor product of groups,

Abstract

In this work we study some structural properties of the group q a non-negative integer, which is an extension of the q-tensor product where G and H are normal subgroups of some group L. We establish by simple arguments some closure properties of when G and H belong to certain Schur classes. This extends similar results concerning the case q = 0 found in the literature. Restricting our considerations to the case G = H, we compute the q-tensor square for q odd, where Dn denotes the dihedral group of order 2n. Upper bounds for the exponent of are also established for nilpotent groups G of class which extend to all similar bounds found by Moravec, P. (2008).
