CONFORMAL SIGMA MODELS WITH ANOMALOUS DIMENSIONS AND RICCI SOLITONS [PDF]

open access: yesModern Physics Letters A, 2005
We present new non-Ricci-flat Kähler metrics with U(N) and O(N) isometries as target manifolds of superconformally invariant sigma models with an anomalous dimension. They are so-called Ricci solitons, special solutions to a Ricci-flow equation. These metrics explicitly contain the anomalous dimension and reduce to Ricci-flat Kähler metrics on the ...

Gradient Weyl-Ricci Soliton [PDF]

open access: yes, 2020
The classical notion of gradient Ricci soliton is extended here to the gradient Weyl-Ricci soliton. A Weyl structure of the base manifold M is lifted to its tangent bundle TM, by using the Sasaki metric.

A New Class of Contact Pseudo Framed Manifolds with Applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2021
In this paper, we introduce a new class of contact pseudo framed (CPF)-manifolds M,g,f,λ,ξ by a real tensor field f of type 1,1, a real function λ such that f3=λ2f where ξ is its characteristic vector field. We prove in our main Theorem 2 that M admits a

Conformal Ricci soliton in para-Sasakian manifolds

open access: yesNovi Sad Journal of Mathematics, 2021
Summary: The object of the present paper is to study \(M\)-projective curvature tensor, pseudo projective curvature tensor, Ricci curvature tensor in para-Sasakian manifold admitting conformal Ricci soliton. We have studied \(M\)-projective semi symmetric para-Sasakian manifolds admitting a conformal Ricci soliton.

Almost Kenmotsu metric as a conformal Ricci soliton [PDF]

open access: yesConformal Geometry and Dynamics of the American Mathematical Society, 2019
In the present paper, we characterize ( k , μ ) ′ (k,\mu )’ and generalized ( k , μ ) ′ (k,\mu )’ -almost Kenmotsu manifolds admitting the conformal Ricci soliton. It is also shown that a

Conformal η-Ricci soliton in Lorentzian para Kenmotsu manifolds

open access: yesGulf Journal of Mathematics, 2023
The objective of the present paper is to study conformal η-Ricci soliton on Lorentzian Para-Kenmotsu manifolds with some curvature conditions. We study Concircular curvature tensor, Quasi conformal curvature tensor, Codazi type of Ricci tensor and cyclic parallel Ricci tensor in Lorentzian Para-Kenmotsu manifolds.

$*$-conformal $\eta-$Ricci solitons on $\epsilon-$para Sasakian manifolds

open access: yesNovi Sad Journal of Mathematics, 2021
Summary: The object of the present paper is to characterize \(\epsilon\)-para Sasakian manifolds admitting \(*\)-conformal \(\eta\)-Ricci solitons. Finally, the existence of \(*\)-conformal \(\eta\)-Ricci soliton in an \(\epsilon\)-para Sasakian manifold is proved by a concrete example.
