Separable solutions of some quasilinear equations with source reaction
Résumé
We study the existence of singular solutions to the equation $-div (|Du|^{p-2}D u)=| u|^{q-1}u$ under the form $u(r,\theta)=r^{-\beta}\omega(\theta)$, $r>0,\theta\in S^{N-1}$. We prove the existence of an exponent $q$ below which no positive solutions can exist. If the dimension is $2$ we use a dynamical system approach to construct solutions.
