摘要

In this paper we deal with the equation −Δpu+|u|p−2u=|u|q−2ufor 1p, under Neumann boundary conditions in the unit ball of RN. We focus on the three positive, radial, and radially non-decreasing solutions, whose existence for q large is proved in Colasuonno et al. (2022). We detect the limit profile as q→∞ of the higher energy solution and show that, unlike the minimal energy one, it converges to the constant 1. The proof requires several tools borrowed from the theory of minimization problems and accurate a priori estimates of the solutions, which are of independent interest.
