Higher-order approximations in the finite element methods
Kolman, Karel ; Křížek, Michal (advisor) ; Feistauer, Miloslav (referee) ; Mlýnek, Jaroslav (referee)
A survey of existing nite element superconvergence theory is conducted. The Steklov postprocessing operator is presented and its properties are investigated, superconvergence bounds are proved. A two-level method for eigenvalue problems is generalized for application to a nonselfadjoint problem. Applications of superconvergence theory to variationally formulated eigenvalue problems are discussed. Numerical experiments documenting the methods are performed.
