Full TextAbstract
We show ¯rst that for each C*-algebra A, contractibility of A implies contractibility of Mn(A). We next prove that an incidence algebra A of upper triangular matrices, de¯ned by a partially ordered set on f1; 2; : : : ; ng satisfying (p; q) 2 ) p · q, is a contractible Banach algebra i® there is no discordant couple of D-transitive triples of elements of
