CL-Transformation on 3-Dimensional Quasi Sasakian Manifolds and Their Ricci Soliton

Mathematics
This paper explores the geometry of 3-dimensional quasi Sasakian manifolds under CL-transformations. We construct both infinitesimal and CL-transformation and demonstrate that the former does not necessarily yield projective killing vector fields.

On eigenfunctions corresponding to first non-zero eigenvalue of the sphere $ S^n(c) $ on a Riemannian manifold

AIMS Mathematics
We recall classical themes such as 'on hearing the shape of a drum' or 'can one hear the shape of a drum?', and the discovery of Milnor, who constructed two flat tori which are isospectral but not isometric.

Curves on Endo-Pajitnov manifolds [PDF]

arXiv
Endo--Pajitnov manifolds are generalizations to higher dimensions of the Inoue surfaces $S^M$. We study the existence of complex submanifolds in Endo--Pajitnov manifolds. We identify a class of these manifolds that do contain compact complex submanifolds and establish an algebraic condition under which an Endo--Pajitnov manifold contains no compact ...

Transit cosmological models in $$F(R,{\bar{T}})$$ F ( R , T ¯ ) gravity theory

European Physical Journal C: Particles and Fields
In the present paper, we investigate some exact cosmological models in $$F(R,{\bar{T}})$$ F ( R , T ¯ ) gravity theory. We have considered the arbitrary function $$F(R, {\bar{T}})=R+\lambda {\bar{T}}$$ F ( R , T ¯ ) = R + λ T ¯ where $$\lambda $$ λ is an
