A Semi-Symmetric Metric γ-Connection in an LP-Sasakian Manifold

Journal of the Tensor Society, 2007
Yano (1970) investiated a semi-symmetric metric connections in a Riemannian manifold and since then many authors studied this connection. Further Mishra and Pandey (1978) defined a semi-symmetric metric ξ-connection in almost contact manifold and obtained various geometrical properties. Following Mishra and Pandey (1978) we define semi-symmetric metric

Studies on Sasakian, Lorentzian para (LP)-Sasakian manifold and other related manifolds

, 2007
Ph.d ThesisThe study of tensors in differentiable manifolds that vary in structure have attracted many researchers. In this thesis out of many newly defined tensors W2 -curvature tensor and W4 -curvature tensor have been studied in Sasaki an, Para ...

A Study on ϕ-Ricci Symmetric LP-Sasakian Manifolds

International Journal of Analysis and Applications
The present paper is devoted to an in-depth study of ϕ-Ricci symmetric LP-Sasakian manifolds, which represent a significant class of Lorentzian para-Sasakian manifolds with rich geometric structures and distinctive curvature characteristics. The notion of ϕ-Ricci symmetry imposes specific constraints on the Ricci tensor in relation to the structure ...

∗-η-Ricci-Yamabe solitons on LP-Sasakian manifolds

Boletim da Sociedade Paranaense de Matemática
In the present note, we characterize LP -Sasakian manifolds endowed with ∗-η-Ricci-Yamabe solitons. Finally, the existence of ∗-η-Ricci-Yamabe solitons in an LP -Sasakian manifold has been proved by constructing a non-trivial example.

On formality of Sasakian manifolds

, 2016
We investigate some topological properties, in particular formality, of compact Sasakian manifolds. Answering some questions raised by Boyer and Galicki, we prove that all higher (than three) Massey products on any compact Sasakian manifold vanish. Hence,
