Deformation theory of nearly K\"ahler manifolds [PDF]

open access: yes, 2016
Nearly K\"ahler manifolds are the Riemannian 6-manifolds admitting real Killing spinors. Equivalently, the Riemannian cone over a nearly K\"ahler manifold has holonomy contained in G2.

The formulation of the Navier–Stokes equations on Riemannian manifolds [PDF]

open access: yes, 2016
We consider the generalization of the Navier–Stokes equation from R n to the Riemannian manifolds. There are inequivalent formulations of the Navier–Stokes equation on manifolds due to the different possibilities for the Laplacian operator acting on ...

Transversal Lightlike Submanifolds of Metallic Semi-Riemannian Manifolds

open access: yes, 2018
The Metallic Ratio is fascinating topic that continually generated news ideas. A Riemannian manifold endowed with a Metallic structure will be called a Metallic Riemannian manifold.

A Geometry Preserving Kernel over Riemannian Manifolds [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2018
- Kernel trick and projection to tangent spaces are two choices for linearizing the data points lying on Riemannian manifolds. These approaches are used to provide the prerequisites for applying standard machine learning methods on Riemannian manifolds ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Low Dimensional Flat Manifolds with Some Elasses of Finsler Metric

open access: yesپژوهش‌های ریاضی, 2020
Introduction An -dimensional Riemannian manifold  is said to be flat (or locally Euclidean) if  locally isometric with the Euclidean space, that is,  admits a covering of coordinates neighborhoods each of which is isometric with a Euclidean domain.

Fast Sequential Clustering in Riemannian Manifolds for Dynamic and Time-Series-Annotated Multilayer Networks

open access: yesIEEE Open Journal of Signal Processing, 2021
This work exploits Riemannian manifolds to build a sequential-clustering framework able to address a wide variety of clustering tasks in dynamic multilayer (brain) networks via the information extracted from their nodal time-series.

Meta-Metallic Riemannian Manifolds

open access: yesSSRN Electronic Journal, 2023
In this study, motivated by the Meta-Golden-Chi ratio, we develop essentially Meta-Metallic manifolds by using Meta-Metallic-Chi ratio and Metallic manifolds, provide an example and explore certain features of its Meta-Metallic structure. We give the conditions for integrability of the almost Meta-Metallic structure and examine its relation

On Slant Riemannian Submersions For Cosymplectic Manifolds [PDF]

open access: yes, 2013
In this paper we introduce slant Riemannian submersions from cosymplectic manifolds onto Riemannian manifolds. We obtain some results on slant Riemannian submersions of a cosymplectic manifolds.

The Geometry of Warped Product Singularities

open access: yes, 2017
In this article the degenerate warped products of singular semi-Riemannian manifolds are studied. They were used recently by the author to handle singularities occurring in General Relativity, in black holes and at the big-bang. One main result presented
