一类混合吸收-反应方程的边界奇异解

Boundary singular solutions of a class of equations with mixed absorption-reaction

Marie-Françoise Bidaut-Veron, Marta Garcia-Huidobro, Laurent Veron

摘要:

研究了满足(E)-- $Δ$ u + up-- M的正函数的性质|$\nabla$使用|q = 0是域$Ω$或当p > 1且1 < q < min{p,2}时在RN+中。本文主要研究(E)在边界上除一点外为零的解。这种分析依赖于RN+中可分解的存在性。我们构造了边界上具有孤立奇点的各种类型的正解。我们还研究了紧边界集的可移除性条件和与(E)相关的具有边界数据测度的狄利克雷问题。

英文摘要:

We study properties of positive functions satisfying (E) --$Δ$u + u p -- M |$\nabla$u| q = 0 is a domain $Ω$ or in R N + when p > 1 and 1 < q < min{p, 2}. We concentrate our research on the solutions of (E) vanishing on the boundary except at one point. This analysis depends on the existence of separable solutions in R N +. We consruct various types of positive solutions with an isolated singularity on the boundary. We also study conditions for the removability of compact boundary sets and the Dirichlet problem associated to (E) with a measure for boundary data.
