Query: HMG -- Homogeneous multigrid for HDG   We introduce a homogeneous multigrid method in the sense that it uses the
same HDG discretization scheme for Poisson's equation on all levels. In
particular, we construct a stable injection operator and prove optimal
convergence of the method under the assumption of elliptic regularity.
Numerical experiments underline our analytical findings.
