Geometry of Stationary Sets for the Wave Equation in Rⁿ, The Case of Finitely Supported Initial Data, An Announcement

الأصل · EN

We consider the Cauchy problem for the wave equation in the whole space, Rⁿ, with initial data which are distributions supported on finite sets. The main result is a precise description of the geometry of the sets of stationary points of the solutions to the wave equation.
