Estimates for Boundary Blowup Solutions of p-Laplacian Type Quasilinear Elliptic Equations

Abstract

In this paper, we investigate the effect of the mean curvature of the boundary ∂Ω on the behavior of the blow-up solutions to the p-Laplacian type quasilinear elliptic equation div(jruj p−2 ru) = u m jruj, p > 1, where the Ω 2 R N be a bounded smooth domain. Under appropriate conditions on p and m, we find the estimates of the solution u interms of the distance from x to the boundary ∂Ω. To the equation div(jruj p−2 ru) = u m jruj q , p > 1, 0 < q < 1, the results of the semilinear problem are extended to the quasilinear ones.
