Some commutants in B(c) which are almost matrices

Billy E. Rhoades and Albert Wilansky

Vol. 49 (1973), No. 1, 211–217
Abstract

We determine necessary and sufficient conditions for two linear operators in B(c) to commute. Specializing one of the operators to be a conservative triangular matrix we determine that most such operators have commutants consisting of almost matrices of a special form.
