摘要:

该文研究在高维外区域中 ($N\geq2$) 的一类半线性双曲型微分不等式非齐次 Dirichlet 外问题. 利用适当选取试验函数的方法及反证技巧, 在依赖于时空变量的非齐次 Dirichlet 边界条件下建立问题解的非存在性定理且导出一些解的存在性结论.

关键词: 双曲型微分不等式, 非齐次 Dirichlet 外问题, 存在性, 非存在性

Abstract:

This paper is concerned with the nonhomogeneous Dirichlet exterior problem for a semilinear hyperbolic differential inequality in the higher dimensional space ($N\geq2$). Using the test function method and contradiction argument, we establish the nonexistence theorem under the nonhomogeneous Dirichlet boundary condition, which depends both on time and space. Meantime, we obtain some existence results.

Key words: Hyperbolic differential inequality, Nonhomogeneous Dirichlet exterior problem, Existence, Nonexistence
