A Berestycki-Lions type result for a class of degenerate elliptic problems involving the Grushin Operator

Claudianor O. Alves, Angelo R. F. de Holanda

摘要:

本文研究了一类半线性退化椭圆型方程$$ -Δ_γ u + a(z)u = f(u) ~~ \mbox{in} ~~ \mathbb{R}^{N}, $$非平凡解的存在性,其中$Δ_γ$称为{ \it Grushin算子},$z:=(x,y)\in\mathbb{R}^{m}\times\mathbb{R}^{k}$和$m+k=N\geq 3$,$f$和$a$是满足某些技术条件的连续函数.为了克服涉及这类算子的一些困难,我们证明了一些紧性结果,这些结果在我们的主要结果的证明中至关重要。对于$a=1$,我们给出了Berestycki-Lions型结果。

英文摘要:

In this work we study the existence of nontrivial solution for the following class of semilinear degenerate elliptic equations $$ -Δ_γ u + a(z)u = f(u) ~~ \mbox{in} ~~ \mathbb{R}^{N}, $$ where $Δ_γ$ is known as the {\it Grushin operator}, $z:=(x,y)\in\mathbb{R}^{m}\times\mathbb{R}^{k}$ and $m+k=N\geq 3$, $f$ and $a$ are continuous function satisfying some technical conditions. In order to overcome some difficulties involving this type of operator, we have proved some compactness results that are crucial in the proof of our main results. For the case $a=1$, we have showed a Berestycki-Lions type result.
