Semi-invariant submanifolds of Kenmotsu manifold immersed in a generalized almost r-contact structure admitting quarter-symmetric non-metric connection

Abstract

We consider a Kenmotsu manifold immersed in  almost $r$-contact manifold admitting a quarter- symmetric non-metric connection and study semi-invariant submanifolds of an almost $r$-contact  Kenmotsu manifold immersed in almost $r$-contact Riemannian manifold endowed with a quarter- symmetric non- metric connection. We also discuss the integrability conditions of distribution on Kenmotsu manifold.
