A posteriori error estimates for non-conforming approximation of eigenvalue problems
(Elsevier Science, 2012-05)
We consider the approximation of eigenvalue problem for the Laplacian by the Crouzeix– Raviart non-conforming finite elements in two and three dimensions. Extending known techniques for source problems, we introduce a ...
A posteriori error estimates of stabilized low-order mixed finite elements for the Stokes eigenvalue problem
(Elsevier Science, 2014-10)
In this paper we obtain a priori and a posteriori error estimates for stabilized low-order mixed finite element methods for the Stokes eigenvalue problem. We prove the convergence of the method and a priori error estimates ...
