Benchmark results for testing adaptive finite element eigenvalue procedures (Q655549)

The authors are interested in a discontinuous Galerkin method employed for highly-accurate eigenvalue computations on a collection of benchmark examples. The \(hp\)-adaptivity based on the approximate solution of appropriate dual problems is used. The effectivity of the computed error estimates is demonstrated on few examples. Further, the problem of partial-differential operators with discontinuous coefficients is considered and a benchmark solution is presented.
