Abstract:
In this paper, we mainly deal with the initial-boundary value problem for the frac- tional damped wave equations
, where s ∈ (0, 1). The operator (−∆)
s is the fractional Laplace operator. In recent years, this operator has
become a research hotspot in physics, financial mathematics, fluid dynamics and oth- er disciplines. At the arbitrary initial energy levels, the local well-posedness of weak solutions to above problem is proved by using Galerkin approximation method and contraction mapping principle under some certain conditions.
