η-Ricci solitons in Kenmotsu manifolds
Annals of the West University of Timisoara: Mathematics and Computer Science, 2019 The object of the present paper is to study generalized weakly symmetric and generalized weakly Ricci symmetric Kenmotsu manifolds whose metric tensor is η-Ricci soliton. The paper also aims to bring out curvature conditions for which η-Ricci solitons in

On generalized weakly symmetric alpha-cosymplectic manifolds
, 2021 This study is concerned with some results on generalized weakly symmetric and generalized weakly Ricci-symmetric alpha-cosymplectic manifolds. We prove the necessary and sufficient conditions for an alpha-cosymplectic manifold to be generalized weakly ...

Weakly Z-symmetric manifolds [PDF]
, 2011 We introduce a new kind of Riemannian manifold that includes weakly-, pseudo- and pseudo projective Ricci symmetric manifolds. The manifold is defined through a generalization of the so called Z tensor; it is named weakly Z-symmetric and is denoted by ...

Isometric immersions into three‐dimensional unimodular metric Lie groups
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.
