Abstract:
Hörmander have presented a remarkable example of a solution of the homogeneous wave equation, which has a singularity at a running point. We are concerned with analytic investigation of this solution for the case of three spatial variables. We describe its support, study its behavior near the singular point and establish its local integrability. We observe that the Hörmander solution is a specialization of a solution found by Bateman five decades in advance.
Key words and phrases:
wave equation, explicit solutions, solutions with a singularity at a running point, Bateman solution, Hörmander solution.
