We consider a Riemannian submersion π: M → N, where M is a CR-submanifold of a locally conformal Kaehler manifold L with the Lee form ω which is strongly non-Kaehler and N is an almost Hermitian manifold. First, we study some geometric structures of N and the relation between the holomorphic sectional curvatures of L and N. Next, we consider the leaves M of the foliation given by ω = 0 and give a necessary and sufficient condition for M to be a Sasakian manifold.

Curvature tensors and Ricci solitons with respect to Zamkovoy connection in anti-invariant submanifolds of trans-Sasakian manifold

Payel Karmakar (2022)

Mathematica Bohemica

The present paper deals with the study of some properties of anti-invariant submanifolds of trans-Sasakian manifold with respect to a new non-metric affine connection called Zamkovoy connection. The nature of Ricci flat, concircularly flat, $ξ$ -projectively flat, $M$ -projectively flat, $ξ$ - $M$ -projectively flat, pseudo projectively flat and $ξ$ -pseudo projectively flat anti-invariant submanifolds of trans-Sasakian manifold admitting Zamkovoy connection are discussed. Moreover, Ricci solitons on Ricci flat,...

Annales de l’institut Fourier

Nous étudions l’ensemble Conf $(M, N)$ des immersions conformes entre deux variétés pseudo-riemanniennes $(M, g)$ et $(N, h)$ . Nous caractérisons notamment l’adhérence de Conf $(M, N)$ dans l’espace des applications continues $𝒞^{0} (M, N)$ , et décrivons quelques propriétés géométriques de $(M, g)$ lorsque cette adhérence est non triviale.
