Abstract
A generalization of a result of Miamee and Salehi on the factorization of positive operator valued functions on a Banach space is given. Also, two decomposition theorems for Banach-space valued stationary processes are proved, and the connections between the existence of moving averages representations and the regularity of a process on the one side and the absolutely continuity of his spectral function and the factorability of the corresponding density on the other side are investigated. Besides, some regularity conditions are discussed.
