Extremals of Log Sobolev inequality on non-compact manifolds and Ricci soliton structures

Calculus of Variations and Partial Differential Equations, 2016
In this paper we establish the existence of extremals for the Log Sobolev functional on complete non-compact manifolds with Ricci curvature bounded from below and strictly positive injectivity radius, under a condition near infinity.

Steady Gradient Kähler-Ricci Solitons on Crepant Resolutions of Calabi-Yau Cones

Memoirs of the American Mathematical Society, 2020
We show that, up to the flow of the soliton vector field, there exists a unique complete steady gradient Kähler-Ricci soliton in every Kähler class of an equivariant crepant resolution of a Calabi-Yau cone converging at a polynomial rate to Cao’s steady ...

Smoothing out positively curved metric cones by Ricci expanders

, 2015
We investigate the possibility of desingularizing a positively curved metric cone by an expanding gradient Ricci soliton with positive curvature operator. This amounts to study the deformation of such geometric structures. As a consequence, we prove that
