Existence for semilinear equations on exterior domains
In this paper we study radial solutions of $\Delta u + K(r)f(u)= 0$ on the exterior of the ball of radius $R>0$ centered at the origin in ${\mathbb R}^{N}$ where $f$ is odd with $f<0$ on $(0, \beta) $, $f>0$ on $(\beta, \infty),$ and $f$ superlinear. The function $K(r)$ is assumed to be pos...
