区域拓扑对椭圆型Kirchhoff问题正解个数的影响

The effect of the domain topology on the number of positive solutions of an elliptic Kirchhoff problem

João R. Santos Júnior

摘要:

利用极大极小方法和Lusternik-Schnirelmann理论,研究了Schrödinger - Kirchhoff方程$$ M\left(\dis\int_{Ω_λ}|\nabla u|^{2}dx+\dis\int_{Ω_λ}u^{2}dx\right)\left[-Δu + u \right]= f(u) $$在$Ω_λ = λΩ$中的多重正解.集合$Ω\subset \mathbb{R}^3$是光滑有界区域,$λ>0$是参数,$M$是一般连续函数,$f$是具有次临界增长的超线性连续函数.我们的主要结果涉及,为大值的$λ$,解决方案的数量与最少的封闭和收缩的$\barΩ$覆盖$\barΩ$。

英文摘要:

Using minimax methods and Lusternik-Schnirelmann theory, we study multiple positive solutions for the Schrödinger - Kirchhoff equation $$ M\left(\dis\int_{Ω_λ}|\nabla u|^{2}dx+\dis\int_{Ω_λ}u^{2}dx\right)\left[-Δu + u \right]= f(u) $$ in $Ω_λ = λΩ$. The set $Ω\subset \mathbb{R}^3$ is a smooth bounded domain, $λ>0$ is a parameter, $M$ is a general continuous function and $f$ is a superlinear continuous function with subcritical growth. Our main result relates, for large values of $λ$, the number of solutions with the least number of closed and contractible in $\barΩ$ which cover $\barΩ$.
