Query: (E,F)-multipliers and applications   For two given symmetric sequence spaces $E$ and $F$ we study the
$(E,F)$-multiplier space, that is the space all of matrices $M$ for which the
Schur product $M\ast A$ maps $E$ into $F$ boundedly whenever $A$ does. We
obtain several results asserting continuous embedding of $(E,F)$-multiplier
space into the classical $(p,q)$-multiplier space (that is when $E=l_p$,
$F=l_q$). Furthermore, we present many examples of symmetric sequence spaces
$E$ and $F$ whose projective and injective tensor products are not isomorphic
to any subspace of a Banach space with an unconditional basis, extending
classical results of S. Kwapie\'{n} and A. Pe{\l}czy\'{n}ski and of G. Bennett
for the case when $E=l_p$, $F=l_q$.
