A STUDY ON CONFORMAL SEMI-INVARIANT RIEMANNIAN MAPS TO COSYMPLECTIC MANIFOLDS

In [3], Akyol and S,ahin introduced the concept of conformal semi -invariant Riemannian maps to almost Hermitian manifolds. In this article, we expand this concept to almost contact metric manifolds as a generalization of totally real submanifolds and semi -invariant Riemannian maps. Herewith, we present conformal semi -invariant Riemannian maps from Riemannian manifolds to cosymplectic manifolds. To ensure the existence of this concept, we prepare a illustrative example, investigate the geometry of the leaves of D-1, D-2,D-1 and D-2 conditions for conformal semi -invariant Riemannian maps to be totally geodesic. We also investigate the harmonicity of such maps. . We find necessary and sufficient
