A hybrid Chebyshev-Tucker tensor format for approximation of multivariate functions
Peter Benner, Boris N. Khoromskij, Venera Khoromskaia +1
We introduce and analyze a mesh-free two-level hybrid Chebyshev-Tucker tensor representation for approximating multivariate functions, which combines tensor-product Chebyshev inter…

Fast tensor-based electrostatic energy calculations in the perspective of protein-ligand docking problem
Peter Benner, Boris N. Khoromskij, Venera Khoromskaia +1
We propose and justify a new approach for fast calculation of the electrostatic interaction energy of clusters of charged particles in constrained energy minimization in the framew…
