报告摘要:In 2017, Bucur-Buttazzo-Nitsch introduced two thermal insulation problem: the energy problem and the eigenvalue problem. In this talk, I will present the stability and concentration breaking result in the energy problem. I will also show that in the eigenvalue problem, as the total mass of the insulating material goes to the symmetry breaking number of a ball, the product of the total mass and the eigenvalue on the ball converge to exactly the half of its range for $m \in (0,\infty)$. Stability of ball shape is also studied in this problem. This is a joint work with Yong Huang and Qiuqi Li from Hunan University.
