报告简介:

In this talk, we are concerned with a class of singularly perturbed elliptic problems in an annulus with supercritical growth. By virtue of a reduction argument, we show that there exists a nodal solution with exactly two positive and two negative peaks, which concentrates on two different orthogonal spheres. In particular, we establish different concentration phenomena of four peaks depending on the parameter. This talk is based on a joint work with Zhisu Liu and Juncheng Wei.
