The Z‐Tensor on Almost Co‐Kählerian Manifolds Admitting Riemann Soliton Structure
Advances in Mathematical Physics, Volume 2024, Issue 1, 2024.A Riemann soliton (RS) is a natural generalization of a Ricci soliton structure on pseudo‐Riemannian manifolds. This work aims at investigating almost co‐Kählerian manifolds (ACKM) 2n+1 whose metrics are Riemann solitons utilizing the properties of the Z‐tensor.

Para-Sasakian geometry in thermodynamic fluctuation theory
, 2015 In this work we tie concepts derived from statistical mechanics, information theory and contact Riemannian geometry within a single consistent formalism for thermodynamic fluctuation theory. We derive the concrete relations characterizing the geometry of

5d Higgs Branch Localization, Seiberg-Witten Equations and Contact Geometry
, 2015 In this paper we apply the idea of Higgs branch localization to 5d supersymmetric theories of vector multiplet and hypermultiplets, obtained as the rigid limit of $\mathcal{N} = 1$ supergravity with all auxiliary fields.

GENERALIZED SASAKIAN SPACE FORMS WITH SEMI-SYMMETRIC METRIC CONNECTIONS
Annals of the Alexandru Ioan Cuza University - Mathematics, 2014 Abstract The aim of the present paper is to introduce generalized Sasakian space forms endowed with semi-symmetric metric connections. We obtain the existence theorem of a generalized Sasakian space form with semi-symmetric metric connection and we give some examples by using warped products endowed with semi-symmetric metric connection.

AxiomsIn the present article, we study submanifolds tangent to the Reeb vector field in trans-Sasakian manifolds. We prove Chen’s first inequality and the Chen–Ricci inequality, respectively, for such submanifolds in trans-Sasakian manifolds which admit a semi-

Invariant Submanifolds of Generalized Sasakian-Space-Forms
, 2019 The object of this paper is to study the invariant submanifolds of generalized Sasakian-space-forms. Here, we obtain some equivalent conditions for an invariant submanifold of a generalized Sasakian-space-forms to be totally geodesic.Comment: 11 ...

The Sasaki Join, Hamiltonian 2-forms, and Sasaki-Einstein Metrics [PDF]
, 2014 By combining the join construction from Sasakian geometry with the Hamiltonian 2-form construction from K\"ahler geometry, we recover Sasaki-Einstein metrics discovered by physicists.

f-biharmonic integral submanifolds in generalized sasakian space forms
Filomat, 2019 We study f-biharmonic integral submanifolds and integral C-parallel submanifolds in generalized Sasakian space forms. As an application, we find the f-biharmonicity conditions for the integral and integral C-parallel submanifolds in Sasakian, ?-Sasakian, Kenmotsu and cosymplectic space forms.

On three-dimensional generalized sasakian space –forms
African Journal of Mathematics and Computer Science Research, 2012 The object of the present paper is to study locally j –symmetric three-dimensional generalized Sasakian space forms and such manifolds with Ricci semi symmetric, h -parallel Ricci tensor and cyclic Ricci tensor. Such space forms with non-null concircular vector field are also considered.
