Description: |
The stability of discrete projections on multiple knot periodic splines on uniform
meshes is studied. Results include their approximation power in Sobolev
spaces, commutator and superapproximation properties. As an application
the convergence of the qualocation method for elliptic periodic pseudodifferential
operators with multiple knot splines as test and trial spaces is analyzed.
