ETNA, Electron. Trans. Numer. Anal. 26, 228-242, electronic only (2007)
Summary: Bounds on eigenvalues which are independent of both degrees of high-order elements and mesh sizes are shown for the system preconditioned by bilinear elements for high-order finite element discretizations applied to a model uniformly elliptic operator.
