Z-Solitons and Gradient Z-Solitons on α-Cosymplectic Manifolds
AxiomsIn this paper, we study Z-solitons and gradient Z-solitons on α-cosymplectic manifolds. The soliton structure is defined by the generalized tensor Z=S+βg, where S denotes the Ricci tensor, g the metric tensor, and β a smooth function.

Cohomogeneity one 4-Dimensional Gradient Ricci Solitons
The Journal of Geometric AnalysisAbstract Simply-connected four-dimensional gradient Ricci solitons that are invariant under a compact cohomogeneity one group action have been studied extensively. However, the special case where the group is $$\textrm{SU}(2)$$

Kähler gradient Ricci solitons with large symmetry
Advances in MathematicsLet $(M, g, J, f)$ be an irreducible non-trivial Kähler gradient Ricci soliton of real dimension $2n$. We show that its group of isometries is of dimension at most $n^2$ and the case of equality is characterized. As a consequence, our framework shows the uniqueness of $U(n)$-invariant Kähler gradient Ricci solitons constructed earlier.
