Functional inequalities for the heat flow on time-dependent metric measure spaces
Eva Kopfer, Karl-Theodor Sturm
We prove that synthetic lower Ricci bounds for metric measure spaces -- both in the sense of Bakry-Émery and in the sense of Lott-Sturm-Villani -- can be characterized by various f…

Super Ricci flows for weighted graphs
Matthias Erbar, Eva Kopfer
We present a notion of super Ricci flow for time-dependent finite weighted graphs. A challenging feature is that these flows typically encounter singularities where the underlying…
