## Tangent flows at infinity of 4-dimensional steady Ricci soliton singularity models

##### Abstract:

We will discuss joint work with R. Bamler, B. Chow, Y. Deng, and Y. Zhang on 4-dimensional steady Ricci soliton singularity models with 3-cylindrical tangent flows at infinity, as well as mention the somewhat parallel work with Y. Zhang on the existence of asymptotic shrinkers on steady solitons with $Ric \geq 0$.
