Abstract

For two Banach spaces X X and Y Y , we denote by K ( X , Y ) K(X,Y) (resp. B ( X , Y ) B(X,Y) ) the space of all compact (resp. bounded) linear operators from X X to Y Y . In this paper, we show that for 1 p , q > 1\leq p,q>\infty , K ( p , q ) K(\ell _{p},\ell _{q}) is an 8-Lipschitz retract of B ( p , q ) B(\ell _{p},\ell _{q}) .
