摘要

We consider the wave equation for the Laplace operator with potential, initial data, and inhomogeneous Dirichlet boundary condition. We establish the existence of a weak solution by using traces and extension domains. We prove the existence, uniqueness, and consistency of a very weak solution for the wave equation with singularities in the potential, initial data, source term, boundary, and boundary condition.
