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