Warped product contact CR-submanifolds of globally framed f-manifolds with Lorentz metric
Published 27 Apr 2012 in math.DG and math.AG | (1204.6125v1)
Abstract: In the present paper, we study globally framed f-manifolds in the particular setting of indefinite S-manifolds for both spacelike and timelike cases. We prove that if $M = N{\perp} \times_f NT$ is a warped CR-submanifold such that $N{\perp}$ is $\phi$?-anti-invariant and NT is $\phi$?-invariant, then M is a CR-product. We show that the second fundamental form of a contact CR warped product of a indefinite S space form satisfies a geometric inequality, $|h|2 \geq p{3|\nabla lnf|2 - \triangle lnf + (c + 2)k + 1}$.
