Infinite dimensional quotients of L_1 by isomorphic subspaces
Let $M$ be a subspace of $L_1(0,1)$. If the subspace $M$ is isomorphic to $L_1(0,1)$ and complemented, then the quotient $L_1(0,1)/M$ is clearly non-reflexive if it is infinite dimensional. So as we …

Bidual of subspaces of $L_1$
Let $M$ be a subspace of $L_1[0,1]$ which is also isomorphic to $L_1[0,1]$. Is it true that $M^{**}$ is complemented in $(L_1[0,1])^{**}$?

Quotients of l^infty
Let $M$ be a closed subspace of $l^\infty$. Suppose that the quotient $l^{\infty}/M$ is isomorphic to $l^\infty$. Is it true that $M$ is complemented in $l^\infty$?
