Tensor product method for fast solution of optimal control problems with fractional multidimensional Laplacian in constraints
Gennadij Heidel, Venera Khoromskaia, Boris N. Khoromskij +1
We introduce the tensor numerical method for solution of the -dimensional optimal control problems with fractional Laplacian type operators in constraints discretized on large $…

Computing the density of states for optical spectra by low-rank and QTT tensor approximation
Peter Benner, Venera Khoromskaia, Boris N. Khoromskij +1
In this paper, we introduce a new interpolation scheme to approximate the density of states (DOS) for a class of rank-structured matrices with application to the Tamm-Dancoff appro…
