A NOTE ON THE RANGE OF COMPACT MULTIPLIERS OF MIXED-NORM SEQUENCE SPACE


Ivan Jovanović, Vladimir Rakočević




In this note we consider the range as a range space of compact multipliers of mixed norm sequence spaces $l^{p,q}, 0 \leqp,q \leq \infty$. In contrast to the general case we show that a compact multiplier always remain compact under reduction of the final space to the range space of multipliers.
