报 告 人:郭千桥,西北工业大学
报告摘要:The paper is concerned with a slightly subcritical elliptic problem with Hardy term. We prove the existence of multi-bubble nodal solutions that blow up positively at the origin and negatively at a different point. In the case of Ω being a ball centered at the origin we can obtain solutions with up to 5 bubbles of different signs. We also obtain nodal bubble tower solutions, i.e. superpositions of bubbles of different signs, all blowing up at the origin but with different blow-up order. The asymptotic shape of the solutions is determined in detail. This is a joint work with Professor Thomas Bartsch.
