The inverse rank and product of tensors
Web22.1 Tensors Products We begin by defining tensor products of vector spaces over a field and then we investigate some basic properties of these tensors, in particular the existence of bases and duality. ... the inverse of the matrix (g ij). The inner product on a finite vector space also yields a natural isomorphism between Webi-inverse (i = 1,2,5) and group inverse of tensors based on a general product of tensors. They explore properties of the generalized inverses of tensors on solving tensor equations and computing formulas of block tensors. The representations for the 1-inverse and group inverse of some block tensors are also established. They then use the 1 ...
