Abstract

For a sequence x = (x(k)), we denote the difference sequence by Delta x = (xk x(k-1)). Let u = (u(k))(k=0)(infinity) and v = (v(k))(k=0)(infinity) be the sequences of real numbers such that u(k) not equal 0, vk not equal 0 for all k is an element of N. The difference sequence spaces of weighted means lambda(u, v, Delta) are defined as
