Uniqueness Theorems for Positive Radial Solutions of Quasilinear Elliptic Equations in a Ball

We establish a new Pohozaev-type identity and use it to prove a theorem on the uniqueness of positive radial solutions to the quasilinear elliptic problem div( um−2emsp14; u)+f(u)=0 inB, andu=0 on ∂B, whereBis a finite ball in n,n 3 and 10 and 1 p
