TLDR
In this article, the authors prove a backwards uniqueness theorem for solutions to the Ricci flow and prove that the isometry group of a solution cannot expand within the lifetime of the solution.
Abstract
In this paper, we prove a backwards uniqueness theorem for solutions to the Ricci flow. A particular consequence is that the isometry group of a solution cannot expand within the lifetime of the solution.

Laplacian flow for closed G2 structures: Shi-type estimates, uniqueness and compactness

TL;DR: In this paper, the authors show that the Laplacian flow will blow up at a finite-time singularity, so the flow will exist as long as the velocity of the flow remains bounded.

Homogeneous Ricci solitons

Michael Jablonski
- 01 Feb 2015 - 
TL;DR: In this paper, it was shown that Ricci solitons are semiautomatically Ricci flow-invariant and Ricci-isometry-based metrics, in the sense that they evolve under the Ricci flows by dilation and pullback by automorphisms of the isometry group.

Uniqueness of self-similar shrinkers with asymptotically conical ends

TL;DR: In this article, the uniqueness of smooth embedded selfshrinkers asymptotic to generalized cylinders of infinite order was shown and non-rotationally symmetric self-shrinking ends were constructed with rate as fast as any given polynomial.

Rigidity of asymptotically conical shrinking gradient Ricci solitons

TL;DR: In this paper, it was shown that if two gradient shrinking Ricci solitons are asymptotic along some end of each to the same regular cone, then the soliton metrics must be isometric on some neighborhoods of infinity of these ends.

Ricci flow of homogeneous manifolds

TL;DR: In this paper, a dynamical system defined on a subset of the variety of Lie algebras, parameterizing the space of all simply connected homogeneous spaces of dimension ρ ≥ 0, with a ρ-dimensional isotropy, which is proved to be equivalent in a precise sense to the Ricci flow, is presented.
