主 题:Blow up rate large positive solution quasi-linear elliptic problem uniqueness.
摘 要:We establish the existence, uniqueness and the blow-up rate of the large positive solution of the quasi-linear elliptic problem -△pu=λ(x)u^θ-1-b(x)h(u), in Ω,with boundary condition u = +∞ on δΩ, where Ω R^N (N≥2) is a smooth bounded domain, 1 〈 p 〈∞ λ(·) and b(·) are positive weight functions and h(u) ~ uq-1 as u → ∞. Our results extend the previous work [Z. Xie, J. Diff. Equ., 247 (2009), 344-363] from case p = 2, λ is a constant and θ = 2 to case 1 〈 p 〈∞, A is a function and 1 ( 0 〈 θ 〈q 〉 p); and also extends the previous work [Z. Xie, C. Zhao, J. Diff. Equ., 252 (2012), 1776-1788], from case A is a constant and θ = p to case λ is a function and 1 〈 θ 〈 q ( 〉 p). Moreover, we remove the assumption of radial symmetry of the problem and we do not require h(·) is increasing.
