內容介紹：We will discuss some results related to several classes of semilinear elliptic equations and evolution equations derived from fields such as Micro-Electro-Mechanical Systems (MEMS). In the first part of this talk, we will examine the behaviors of rupture solutions for a class of elliptic MEMS equations in . We will first analyze the classification of all possible singularities at the rupture point for rupture solutions . In particular, we show that sometimes admits only the isotropic singularity at , and otherwise may admit an anisotropic singularity at . Secondly, global solutions in (their existence and their behavior near as well as near ) are also studied. In the second part, we will discuss the asymptotic behaviors of global solutions of two types of MEMS equations (nonlocal second-order MEMS equations and fourth-order MEMS equations with Dirichlet boundary conditions), for which the comparison principle is not available. This is a joint work with Y.J. Guo, F. Zhou, Qing Li, Yufei Wei, and Wenlong Wu.
