In this talk, we will discuss how Ricci flow smoothing can be used to produce expanding Ricci solitons coming out of a metric cone, when the curvature is non-negative. We will discuss how its relation to problem in Hamilton-Lott pinching conjecture...

In this talk, we will consider Riemannian metrics with scalar curvature bounded from below and discuss the possible behavior of the sequence under various non-collapsing assumption. This is based on joint works with A. Naber, R. Neumayer, P. Topping...
