FACTORIZATION OF SOME SUBSPACES WITH RESPECT TO A BILINEAR MAP

Let f: XY Z be a bilinear mapping, on normed spaces and M, N and W are closed subspaces of X, Y, and Z, respectively. In this paper, we dene the factorization property of W on MN, with respect to f, and then we study the subspaces which factor on special subspaces with respect to some module actions.
