Non-singular multilinear forms and certain ๐-way matrix factorizations
Introduction.Let there be given a p-way matrix A = (ยซ<,...<,), ii, โข โข โข , iP = l, โ โ โ , n.The operation which takes A into A' = (ail...ipbilil), where B = (bivi) is a non-singular 2-way matrix and the repeated index indicates summation, is called a non-singular โฆ
