Structure at infinity of expanding gradient Ricci soliton

Chih-Wei Chen, Alix Deruelle

We study the geometry at infinity of expanding gradient Ricci solitons of dimension greater than two with finite asymptotic curvature ratio without curvature sign assumptions. We m…

Steady gradient soliton with curvature in L^1

Alix Deruelle

We characterize complete nonnegatively curved steady gradient soliton with curvature in L^1. We show that there are isometric to a product (R^2,g_{cigar}) times(R^{n-2}, eucl))/Gam…
