Abstract

In this paper, firstly we investigate conditions under which the action of an operator on a KK-frame, remain again a KK-frame for Hilbert module E. We also give a generalization of Douglas Theorem and we shall use it to prove the sum of two KK-frame under certain condition is again a KK-frame. Finally, we characterize the KK-frame generators for a unitary system in terms of operators.
