The Geometry of Differential Harnack Estimates
Sebastian Helmensdorfer, Peter Topping
In this short note, we hope to give a rapid induction for non-experts into the world of Differential Harnack inequalities, which have been so influential in geometric analysis and…

Space-time constructions for the mean curvature flow in a Ricci flow background
Sebastian Helmensdorfer
Given a solution of the (backwards) Ricci flow one can construct a so called canonical soliton metric on space-time, introduced by E. Cabezas-Rivas and P. Topping. We observe that…

A model for the behaviour of fluid droplets based on mean curvature flow
Sebastian Helmensdorfer
During his experiments W. D. Ristenpart made a very remarkable discovery. If two oppositely charged droplets of fluid are close enough, at first they attract each other and touch e…
