主 题:p-Lapacian Hardy potential symmetry uniqueness asymptotic behavior
摘 要:We study a nonlinear equation in the half-space with a Hardy potential,specifically,−Δ_(p)u=λu^(p−1)x_(1)^(p)−x_(1)^(θ)f(u)in T,where Δp stands for the p-Laplacian operator defined by Δ_(p)u=div(∣Δu∣^(p−2)Δu),p1,θ−p,and T is a half-space{x_(1)0}.When λΘ(where Θ is the Hardy constant),we show that under suitable conditions on f andθ,the equation has a unique positive ***,the exact behavior of the unique positive solution as x_(1)→0^(+),and the symmetric property of the positive solution are obtained.
