ORTHOGONAL DECOMPOSITIONS IN HILBERT C-MODULES AND STATIONARY PROCESSES
D. POPOVICI
Abstract. 
It is obtained a Wold-type decomposition for an adjointable isometry on a Hilbert $ C$-module which is sequentially complete with respect to some locally convex topology, denoted by $s$. Particularly self-dual Hilbert $ C$-modules satisfy this condition. Finally, as an application we shall give a new proof of the Wold decomposition theorem for discrete stationary processes in complete correlated actions.
