THE CONSERVATIVE MATRIX ON LOCALLY CONVEX SPACES

Let (X, τX) and (Y, τY) be locally convex spaces, c(X) and c(Y) the X-valued and Y-valued convergent sequence spaces, respectively, Aij ϵ L(X, Y) and A = (Aij) an operator-valued infinite matrix. In this paper, we characterize the matrix A = (Aij) which transforms c(X) into c(Y). As its applications...

Summary:Let (X, τX) and (Y, τY) be locally convex spaces, c(X) and c(Y) the X-valued and Y-valued convergent sequence spaces, respectively, Aij ϵ L(X, Y) and A = (Aij) an operator-valued infinite matrix. In this paper, we characterize the matrix A = (Aij) which transforms c(X) into c(Y). As its applications, we introduce the chi function χ on locally convex spaces, and show that a conservative matrix is conull if and only if χ(A) = 0.
