Title: | Uniqueness and Layer Analysis for Boundary Blow-up Solutions | Contributor(s): | Du, Y (author) ; Guo, Z (author) | Publication Date: | 2004 | DOI: | 10.1016/j.matpur.2004.01.006 | Handle Link: | https://hdl.handle.net/1959.11/434 | Abstract: | We prove uniqueness for boundary blow-up solutions of the problem:Δu=λf(u) in Ω,u|∂Ω=∞, with large λ. Previous uniqueness results require a monotonicity assumption for f(u)lu in the entire range of the boundary blow-up solutions. By obtaining good boundary layer estimates for large λ, we obtain uniqueness under much weaker assumptions on f(u). Our estimates for the layers of the boundary blow-up solutions have independent interest, and may have other applications. | Publication Type: | Journal Article | Source of Publication: | Journal de Mathematiques Pures et Appliquees, 83(6), p. 739-763 | Publisher: | Elsevier Masson | Place of Publication: | France | ISSN: | 1776-3371 0021-7824 |
