Triangular Products of Group Representations and Their Applications (Softcover Reprint of the Original 1st 1981) After 8 books environments ranging from the unwittinglyThe construction considered in these notes is based on a very simple idea. Let (A, G ) and (B, G ) be two group representations, for definiteness faithful and finite 1 2 dimensional, over an arbitrary field. We shall say that a faithful representation (V, G) is an extension of (A, G ) by (B, G ) if there is a G submodule W of V such that 1 2 the naturally arising representations (W, G) and (V W, G) are isomorphic, modulo their kernels, to (A, G ) and
