Results of Hyperbolic Ricci Solitons
Symmetry, 2023 We obtain some properties of a hyperbolic Ricci soliton with certain types of potential vector fields, and we point out some conditions when it reduces to a trivial Ricci soliton. We also study those soliton submanifolds whose vector fields are the tangential components of a concurrent vector field on the ambient manifold, and in particular, we show ...

Almost $\eta-$Ricci Solitons on Pseudosymmetric Lorentz Sasakian Space Forms
Communications in Advanced Mathematical Sciences, 2023 In this paper, we consider pseudosymmetric Lorentz Sasakian space forms admitting almost $\eta-$Ricci solitons in some curvature tensors. Ricci pseudosymmetry concepts of Lorentz Sasakian space forms admits $\eta-$Ricci soliton have introduced according ...

A Note on Kahler-Ricci Soliton [PDF]
International Mathematics Research Notices, 2009 In this note we provide a proof of the following: Any compact KRS with positive bisectional curvature is biholomorphic to the complex projective space. As a corollary, we obtain an alternative proof of the Frankel conjecture by using the Kähler-Ricci flow.

$\ast$-Ricci soliton on GSSF with Sasakian metric [PDF]
, 2022 We study generalized Sasakian-space-forms (GSSF) $M^{2n+1} (k_1, k_2, k_3)$ with Sasa\-kian metric admitting $\ast$-Ricci soliton. We obtain that either such GSSF has $k_1=\frac{2n+1}{2n+2}$, $k_2= k_3=-\frac{1}{2n+2}$ and $\ast$-soliton is steady or ...

Randers Ricci soliton homogeneous nilmanifolds [PDF]
, 2021 Let $F$ be a left-invariant Randers metric on a simply connected nilpotent Lie group $N$, induced by a left-invariant Riemannian metric $\hat{\boldsymbol{a}}$ and a vector field $X$ which is $I_{\hat{\boldsymbol{a}}}(M)$-invariant.
