Title:A free boundary problem for modelling plaques in the artery

Time: Sun, June.10, 2018 , PM:4:00-5:00.

Location: Room 4318, Building No.4, Wushan Campus

Abstract:

  In this talk, we consider a model of plaque growth, which satisfy a coupled system of PDEs with a free boundary, the interface between the plaque and the blood flow. We prove that there exist small radially symmetric stationary plaques and establish a sharp condition that ensures their stability. We also determine necessary and sufficient conditions under which a small initial plaque will shrink and disappear, or persist for all times.
