We consider blow-up results for a system of inhomogeneous wave inequalities in exterior domains. We will handle three type boundary conditions: Dirichlet type, Neumann type and mixed boundary conditions. We use a unified approach to show the optimal criteria of Fujita type for each case. Our study yields naturally optimal nonexistence results for the corresponding stationary wave system and equation. We provide many new results and close some open questions.

外域非均匀波不等式系统的 Fujita 型临界准则

我们考虑外部域中非均匀波不等式系统的爆炸结果。我们将处理三种类型的边界条件:Dirichlet 型、Neumann 型和混合边界条件。我们使用统一的方法来显示每个案例的 Fujita 类型的最佳标准。我们的研究为相应的驻波系统和方程产生了自然最优的不存在结果。我们提供了许多新结果并关闭了一些悬而未决的问题。
