Abstract: The limit behavior of immortal Ricci flows with appropriate curvature conditions are important in the application of Ricci flows to hunt for canonical metrics. In this talk, we will discuss how to simplify the singularity structure of the limit space as a result of the evolution of immortal Ricci flows with bounded or decaying curvature. To deal with the major difficulty of possible collapsing along the Ricci flow in the long time, we will present some new tools in understanding the metric measure structure of the collapsing geometry.
