On Invariant Submanifolds of a Nearly Trans-Sasakian Manifold

, 2011
In this paper, invariant submanifolds of a nearly trans-Sasakian manifold are studied. Necessary and sufficient conditions are given to make a submanifold of a nearly trans-Sasakian manifold an invariant submanifold.

Rotationally invariant texture features using the dual-tree complex wavelet transform [PDF]

, 2000
New rotationally invariant texture feature extraction methods are introduced that utilise the dual-tree complex wavelet transform (DT-CWT). The complex wavelet transform is a new technique that uses a dual tree of wavelet filters to obtain the real and ...

TOTALLY UMBILICAL SEMI-INVARIANT SUBMANIFOLDS AND CR-SUBMANIFOLDS OF A SASAKIAN MANIFOLD

Tamkang Journal of Mathematics, 1993
In the present paper, a classification theorem for totally um- bilical semi-invariant submanifold is established. CR-submanifolds of a Sasakian space form are studied in detail, and finally a theorem for a CR- submanifold of a Sasakian manifold to be a proper contact CR-product is proved.

Anti-invariant submanifolds of locally decomposable golden Riemannian manifolds

, 2020
In this paper, we give some properties of anti-invariant submanifolds of a golden Riemannian manifold. We obtain some necessary conditions for any submanifold in a locally decomposable golden Riemannian manifold to be anti-invariant. In these conditions,

Formulation and proof of the gravitational entropy bound

Journal of High Energy Physics
We provide a formulation and proof of the gravitational entropy bound. We use a recently given framework which expresses the measurable quantities of a quantum theory as a weighted sum over paths in the theory’s phase space.

Two theorems on invariant submanifolds of product Riemannian manifold

, 2003
In this paper we discuss the distributions of a Riemannian almost-product structure in product Riemannian manifold. We show that an invariant submanifold of a product Riemannian manifold has a Riemannian almost-product structure, and investigate ...

Chen-Type Inequalities for PS-Submanifolds in Complex Space Forms

Axioms
In this paper, we investigate Chen’s δ-invariant for partially slant (PS) submanifolds of complex space forms. A PS-submanifold admits an orthogonal decomposition of the tangent bundle into a proper slant distribution and an arbitrary ambiguous ...

A holistic similarity measure for GMMs by embedding it into the manifold of SPD matrices

Applied Mathematics in Science and Engineering
In this paper, a new similarity measure for comparing two Gaussian Mixture Models (GMMs) is obtained. This is based on an embedding of the manifold of K-component GMMs into the manifold of the symmetric positive definite matrices (SPD).
