An integrable nineteen vertex model lying on a hypersurface

open access: yesNuclear Physics B, 2015
We have found a family of solvable nineteen vertex model with statistical configurations invariant by the time reversal symmetry within a systematic study of the respective Yang–Baxter relation.

On six-dimensional Vaisman — Gray submanifolds of the octave algebra

open access: yesДифференциальная геометрия многообразий фигур, 2019
The W1 + W4 class of almost Hermitian manifolds (in accordance with the Gray — Hervella classification) is usually named as the class of Vaisman — Gray manifolds.

Invariant Submanifolds of a Lorentzian β-Kenmotsu Manifold

open access: yesAmesia
In this paper we have investigated invariant submanifolds of Lorentzian β-Kenmotsu manifolds and obtained the necessary and sufficient conditions for total geodesic submanifolds of Lorentzian β-Kenmotsu manifolds. We have considered pseudoparallel, 2-pseudoparallel, Ricci generalized pseudoparallel, Ricci generalized 2-pseudoparallel submanifolds of ...

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

open access: yesTamkang 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.

Formulation and proof of the gravitational entropy bound

open access: yesJournal 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.

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

open access: yesAxioms
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

open access: yesApplied 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).

Gradient Expanding Ricci Solitons Type Inequalities on Submanifolds in Quaternion Kaehler Manifolds with Bi-Slant Factor

open access: yesMathematics
In this article, we study the Ricci soliton on quaternion bi-slant submanifolds of quaternion Kaehler manifolds. We obtain a lower-bound-type inequality in terms of expanding gradient Ricci solitons with a gradient-type vector field for the quaternion bi-

A unified dynamical systems framework for cosmology in f(Q) gravity: generic features across the connection branches

open access: yesEuropean Physical Journal C: Particles and Fields
We develop a unified dynamical systems framework for spatially flat FLRW cosmology in f(Q) gravity, covering all three connection branches using a single set of Hubble-normalised variables without fixing the function f(Q) a priori. This model-independent
