CR-submanifolds of Lorentzian manifolds

open access: yes, 2009
This paper is about the talk given in the VIth Geometry Symposium in Bursa, Turkey, on July 2008. We present the notion of CR-submanifolds of a Lorentzian almost contact manifold, study their principal characteristics and the particular cases in which the manifold is Lorentzian Sasakian manifold or a Lorentzian Sasakian space form.

CR-SUBMANIFOLDS OF HYPERBOLICAL ALMOST HERMITIAN MANIFOLDS

open access: yesDemonstratio Mathematica, 1990
Summary: The aim of this paper is to study the class of CR-submanifolds of hyperbolical almost Hermitian manifolds, by following the same ideas of those used in the case of CR-submanifolds of almost Hermitian manifolds [\textit{A. Bejancu}, Geometry of CR-submanifolds (1986; Zbl 0605.53001)].

CONTACT CR-SUBMANIFOLDS OF A NEARLY SASAKIAN MANIFOLD

open access: yesDemonstratio Mathematica, 1996
Let \(\Sigma=(\varphi,\xi,\eta,g)\) be an almost contact metric structure on a manifold \(M\) consisting of a (1,1) tensor field \(\varphi\), a vector field \(\xi\), a 1-form \(\eta\), and a Riemannian metric \(g\) satisfying \(\varphi^2=-I+\eta\otimes\xi\), \(\eta(\xi)=1\), \(\eta(X)=g(X,\xi)\), \(g(\varphi X,\varphi Y)=g(X,Y)-\eta(X)\eta(Y)\).

ON CR SUBMANIFOLDS OF LOCALLY CONFORMAI KAEHLER MANIFOLDS

open access: yesDemonstratio Mathematica, 1986
Characterizations of several classes of CR-submanifolds of locally conformal Kaehler manifolds are obtained. Anti-invariant submanifolds immersed in locally conformal Kaehler manifolds are studied in detail.
