Abstract

In the present paper we introduce the generalized inverse operators which have an interesting role in operator theory. We establish Douglas' factorization theorem type for Hilbert pro-CC^{\ast}-module. We introduce the notion of atomic system and of KK-frame in Hilbert pro-CC^{\ast}-module and we study the relationship between them. We also demonstrat some properties of KK-frame by using Douglas' factorization theorem.Finally we demonstrate that the sum of two KK-frames in a Hilbert pro-CC^{\ast}-module with certain conditions is once again a KK-frame.
