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
