Positive radial solutions involving nonlinearities with zeros
In this paper we consider the non-autonomous quasilinear elliptic problem \begin{document}$ \begin{cases} -\Delta_p u = \lambda |x|^{\delta} f(u) &\mbox{in }B_1(0)\\ u = 0 &\mbox{in }\partial B_1(0), \end{cases} $\end{document} where $ f:\mathbb{R}\to[0,\infty) $ is a nonnegative $ C^1- $function with $ f(0) = 0 $, $ f(U) = 0 $ for …
