Abstract
A lower triangular infinite matrix is called a triangle if there are no zeros on the principal diagonal. The main result of this paper gives a minimal set of sufficient conditions for a triangle T : Ak → Ak for the sequence space Ak defined as follows:Ak := {{sn} : ∑ ^∞ n=1 n^k−1 | an|^k ∞ , an = sn − sn−1 }.
Keywords
