Multiple nonradial solutions for a nonlinear elliptic radial problem: an improved result. (arXiv:1810.09372v1 [math.AP])
来源于:arXiv
We obtain an improved version of a recent result concerning the existence of
nonnegative nonradial solutions $u\in D^{1,2}(\mathbb{R}^{N})\cap
L^{2}(\mathbb{R}^{N},\left| x\right| ^{-\alpha }dx)$ to the equation \[
-\triangle u+\displaystyle\frac{A}{\left| x\right| ^{\alpha }}u=f\left(
u\right) \quad \text{in }\mathbb{R}^{N},\quad N\geq 3,\quad A,\alpha >0, \]
where $f$ is a continuous nonlinearity satisfying $f\left( 0\right) =0$. 查看全文>>
