The object of the present paper is to study weakly concircular symmetric and weakly concircular Ricci symmetric Kenmotsu manifolds.

We combine recent developments on weakly symmetric pseudo--riemannian nilmanifolds with geometric methods for construction of unitary representations square integrable Dolbeault cohomology spaces. This runs parallel to discrete series spaces harmonic forms values in holomorphic vector bundles over flag domains. Some special cases had been described by Satake 1971 and the author 1975. Here we de...

In this paper, we define the concept of compatible and weakly compatible mappings in b-metric spaces and inspired by the Ciric and et. al method, we produce appropriate conditions for given the unique common fixed point for a family of the even number of self-maps with together another two self-maps in a complete b-metric spaces. Also, we generalize this common fixed point theorem for a seq...
