Query: DPG method with optimal test functions for a fractional advection
  diffusion equation   We develop an ultra-weak variational formulation of a fractional advection
diffusion problem in one space dimension and prove its well-posedness. Based on
this formulation, we define a DPG approximation with optimal test functions and
show its quasi-optimal convergence. Numerical experiments confirm expected
convergence properties, for uniform and adaptively refined meshes.
