Resumen de Effective constructions of separable quotients of Banach spaces

Marek Wójtowicz

• A simple way of obtaining separable quotients in the class of weakly countably determined (WCD) Banach spaces is presented (Theorem 1). A large class of Banach lattices, possessing as a quotient $c_0, l_1, l_2$, or a reflexive Banach space with an unconditional Schauder basis, is indicated (Theorem 2).
