Solvability and microlocal analysis of the fractional Eringen wave equation
  We discuss unique existence and microlocal regularity properties of Sobolev
space solutions to the fractional Eringen wave equation, initially given in the
form of a system of equations in which the classical non-local Eringen
constitutive equation is generalized by employing space-fractional derivatives.
Numerical examples illustrate the shape of solutions in dependence of the order
of the space-fractional derivative.
