Abstract

Let A=(ank) be an infinite matrix with all ank0 and P a bounded, positive real sequence. For normed spaces E and Ek the matrix A generates paranormed sequence spaces such as [A,P]((Ek)), [A,P]0((Ek)), and [A,P](E) which generalize almost all the existing sequence spaces, such as l, c0, c, lp, wp, and several others. In this paper, conditions under which these three paranormed spaces are separable, complete, and r-convex, are established.
