论文摘要
给定$ k \ in \ mathbb n $，我们定义了一类连续的分段函数$ f $具有突然但受控的幅度变化，以使问题$ $ΔuΔU +f（u）= 0，\ quad x \ in \ mathbb r^n，n> 2，n> 2，$ k $ g $ radyally对称的基础解决方案。
Given $k\in\mathbb N$, we define a class of continuous piecewise functions $f$ having abrupt but controlled magnitude changes so that the problem $$Δu +f(u)=0,\quad x\in \mathbb R^N, N> 2, $$ has at least $k$ radially symmetric ground state solutions.
