Abstract:
In the present paper we define subclasses of locally decomposable Riemannian space, i. e. the class of the almost recurrent and the class of the almost Ricci recurrent locally decomposable Riemannian spaces. In these cases we find that the almost recurrence covectors are decomposable. Theorem 2 (resp. Theorem 3) characterizes the class of the almost recurrent (resp. of the almost Ricci recurrent) spaces.
