 A note on M-ideals of compact operators Bull. Korean Math. Soc. 1998 Vol. 35, No. 4, 683-687 Chong-Man Cho and Beom Sool Kim Hanyang University, Hanyang University Abstract : Suppose $X$ is a closed subspace of $\sumX$, $\dim X_n$ $< \infty$, which has the metric compact approximation property. It is proved that if $Y$ is a Banach space of cotype $q$ for some $2 \leq q < \infty$ then $K(X,Y)$ is an $M$-ideal in $L(X,Y)$. Keywords : compact operator, M-ideal, cotype $q$, the metric compact approximation MSC numbers : 46A32, 41A50 Downloads: Full-text PDF
