Abstract:
We present the solution of the Cauchy problem (the initial-value problem in the whole space) for the wave equation with infinite-dimensional Lévy Laplacian ΔL,
∂2U(t,x)∂t2=ΔLU(t,x)
in two function classes, the Shilov class and the Gâteaux class.
Keywords:
wave equation, hyperbolic equation, Lévy Laplacian, Cauchy problem, Shilov function class, Gâteaux function class, Hilbert space, variational derivative.
