Warped product CR-submanifolds of cosymplectic manifolds

摘要

In the present paper, we study warped product CR-submanifolds of cosymplectic manifolds. It is shown that the warped product of the type ${N_perptimes{_f}N_T}$ is trivial and obtain a characterization result for the warped product of the type ${N_Ttimes{_f}N_perp}$ , where N T and ${N_perp}$ are invariant and anti-invariant submanifolds of a cosymplectic manifold ${bar M}$ , respectively.
