双参数$(p,q)$ -Laplace方程正解的多重性

Multiplicity of positive solutions for $(p,q)$-Laplace equations with two parameters

Vladimir Bobkov, Mieko Tanaka

摘要:

研究了方程$-Δ_p u -Δ_q u = α|u|^{p-2}u+β|u|^{q-2}u$在有界区域$Ω\subset \mathbb{R}^N$中的零狄利克雷问题,其中有$1<q<p$ .研究了$(α,β)$ -平面上对应于特殊正解存在阈值的两条临界曲线之间的关系。特别是,在某些邻域的点$(α,β) = \left(\|\nabla φ_p\|_p^p/\|φ_p\|_p^p, \|\nabla φ_p\|_q^q/\|φ_p\|_q^q\right)$,其中$φ_p$是第一本征函数的$p$ -拉普拉斯算子,我们显示存在两个,这是相当意外的,三个不同的正解,取决于指数之间的关系$p$和$q$。

英文摘要:

We study the zero Dirichlet problem for the equation $-Δ_p u -Δ_q u = α|u|^{p-2}u+β|u|^{q-2}u$ in a bounded domain $Ω\subset \mathbb{R}^N$, with $1<q<p$. We investigate the relation between two critical curves on the $(α,β)$-plane corresponding to the threshold of existence of special classes of positive solutions. In particular, in certain neighbourhoods of the point $(α,β) = \left(\|\nabla φ_p\|_p^p/\|φ_p\|_p^p, \|\nabla φ_p\|_q^q/\|φ_p\|_q^q\right)$, where $φ_p$ is the first eigenfunction of the $p$-Laplacian, we show the existence of two and, which is rather unexpected, three distinct positive solutions, depending on a relation between the exponents $p$ and $q$.
