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)].

Quaternion CR-submanifolds of quaternion manifolds

open access: yesKodai Mathematical Journal, 1981
A quaternion manifold (or quaternion Kaehlerian manifold [10]) is defined as a Riemannian manifold whose holonomy group is a subgroup of Sp(l). Sp(m)=Sp(l)xSp(m)/{±1}. The quaternion projective space QP, its noncompact dual and the quaternion number space Q are three important examples of quaternion manifolds.

CR-Submanifolds of Generalized -Space Forms [PDF]

open access: yesGeometry, 2013
We study sectional curvature, Ricci tensor, and scalar curvature of submanifolds of generalized -space forms. Then we give an upper bound for foliate -horizontal (and vertical) CR-submanifold of a generalized -space form and an upper bound for minimal -horizontal (and vertical) CR-submanifold of a generalized -space form.

Microlocal complex foliation of R-Lagrangian CR submanifolds

open access: yesTsukuba Journal of Mathematics, 1997
Let \(X\) be a complex manifold and \(X^R\) be the real analytic manifold underlying \(X\). Consider a submanifold \(M\) of \(X^R\) and suppose that the conormal bundle \(T^*_MX\) is regular and CR in the cotangent bundle \(T^*X\). The author proves that \(T^*_MX\) is locally defined on the zero set of the real and/or imaginary part of holomorphic ...

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.
