Abstract
  We study the theory of best approximation in tensor product and the direct sum of some lattice normed spacesX_{i}. We introduce quasi tensor product space and discuss about the relation between tensor product space and thisnew space which we denote it by X boxtimes Y. We investigate best approximation ...  Read More
