报告摘要：The presentation concerns the effective and reliable computation of PDE eigenvalue computation of a model Poisson problem with adaptive mesh-refining algorithms.

The reliable a posteriori error control of some finite element discretisation is reviewed on the black board from the literature even based on the Chapter in the finite element textbook of Strang and Fix. Newer a~posteriori error estimators and adaptive algorithms are discussed based on the PhD dissertations of J. Gedicke and D. Gallistl in recent years. The treatment of eigenvalue clusters and the localization of eigenvalues will be mentioned as well as the optimal convergence and possible optimal complexity.
