Subspace method for multiparameter-eigenvalue problems based on tensor-train representations
Koen Ruymbeek, Karl Meerbergen, Wim Michiels
In this paper we solve -parameter eigenvalue problems (EPs), with any natural number by representing the problem using Tensor-Trains (TT) and designing a method based on…

Tensor-Krylov method for computing eigenvalues of parameter-dependent matrices
Koen Ruymbeek, Karl Meerbergen, Wim Michiels
In this paper we extend the Residual Arnoldi method for calculating an extreme eigenvalue (e.g. largest real part, dominant,...) to the case where the matrices depend on parameters…
