Title: Hyper-elastic Ricci Flow
Speaker: Prof. Marshall Slemrod (University of Wisconsin-Madison)
Time: 2019 November 5th, 11:00am~12:00pm
In this talk, I will introduce the concept of hyper-elastic Ricci flow. The equation of hyper-elastic Ricci flow amends the classical Ricci flow by the addition of Cauchy stress tensor which itself is derived from the free energy. The main implication of the theory is a uniformization of material behavior which follows from application of a parabolic minimum principle.
