Commutants of some quasi-Hausdorff matrices

Billy E. Rhoades

Vol. 52 (1974), No. 2, 513–517
Abstract

Let B(c) denote the Banach algebra of bounded linear operators over c, the space of convergent sequences, and Γ the subalgebra of conservative infinite matrices. Given an upper triangular matrix A in Γ, a sufficient condition is established for the commutant of A in Γto be upper triangular. Also determined is the commutant, in B(c), of certain quasi-Hausdorff matrices.
