On isometry groups of gradient Ricci solitons
Forum mathematicumWe give a result estimating the dimension of the Lie algebra of Killing vector fields on an irreducible non-trivial gradient Ricci soliton. Then we study the structure of this manifold when the maximal dimension is attained.

On the fundamental group of steady gradient Ricci solitons with nonnegative sectional curvature
Proceedings of the American Mathematical SocietyIn this paper, we study the fundamental group of the complete steady gradient Ricci soliton with nonnegative sectional curvature. We prove that the fundamental group of such a Ricci soliton is either trivial or infinite.

Remarks on non-compact gradient Ricci solitons
, 2009In this paper we show how techniques coming from stochastic analysis, such as stochastic completeness (in the form of the weak maximum principle at infinity), parabolicity and Lp-Liouville type results for the weighted Laplacian associated to the ...

In the first part of the paper we derive integral curvature estimates for complete gradient shrinking Ricci solitons. Our results and the recent work in M. Fernandez-Lopez and E. Garcia-Rio, Rigidity of shrinking Ricci solitons in Math. Z.

On a Classification of 4-d Gradient Ricci Solitons with Harmonic Weyl Curvature
, 2016We study a characterization of 4-dimensional (not necessarily complete) gradient Ricci solitons (M, g, f) which have harmonic Weyl curvature, i.e., $$\delta W=0$$δW=0.
