考虑平面上光滑有界区域上的半线性Lane-Emden问题。本文的目的是分析非线性项的指数p趋于无穷大时变号解的渐近行为。在其他结果中,我们表明,根据一些对称性假设的域,一个家庭的对称解决方案的正负部分集中在同一点上,作为p到无穷大,和极限配置文件看起来像一个塔的两个泡沫所给出的一个叠加的一个定期和一个奇异的解决方案的刘维尔问题在平面上。
We consider the semilinear Lane-Emden problem in a smooth bounded domain of the plane. The aim of the paper is to analyze the asymptotic behavior of sign changing solutions as the exponent p of the nonlinearity goes to infinity. Among other results we show, under some symmetry assumptions on the domain, that the positive and negative parts of a family of symmetric solutions concentrate at the same point, as p goes to infinity, and the limit profile looks like a tower of two bubbles given by a superposition of a regular and a singular solution of the Liouville problem in the plane.
