Uniqueness of the boundary behavior for large solutions to a degenerate elliptic equation involving the ∞–Laplacian

Abstract

In this note we estimate the maximal growth rate at the boundary of viscosity solutions to −∆∞u + λ|u| m−1 u = f in Ω (λ > 0, m > 3).In fact, we prove that there is a unique explosive rate on the boundary for large solutions. A version of Liouville Theorem is also obtained when Ω = R N
