On quotients of Banach spaces having shrinking unconditional bases

Abstract

It is proved that if a Banach space YY is a quotient of a Banach space having a shrinking unconditional basis, then every normalized weakly null sequence in YY has an unconditional subsequence. The proof yields the corollary that every quotient of Schreier's space is coc_o-saturated.
