摘要: A basic question is whether Ricci flow is related to 4-dimensional topology. The answer to this question is
unknown. However, one may begin to speculate on what 4-dimensional Ricci flow might look like geometrically
during finite time. We discuss the potential impact on singularity theory of the work of Munteanu and Wang and
others on gradient Ricci solitons.
