One of the main aims in the theory of matrices is to find necessary and sufficient conditions for the elements
of any matrix so that the corresponding matrix operator maps continuously from one normed space into
another one. Thus, it is very important to find the norm of the matrix operator, at least, to find upper and
lower estimates of it. This problem in Lebesgue spaces of ...
