B-Spline Quarklets and Biorthogonal Multiwavelets
Marc Hovemann, Anne Kopsch, Thorsten Raasch +1
We show that B-spline quarks and the associated quarklets fit into the theory of biorthogonal multiwavelets. Quark vectors are used to define sequences of subspaces of…

Real eigenstructure of regular simplex tensors
Adam Czaplinski, Thorsten Raasch, Jonathan Steinberg
We are concerned with the eigenstructure of supersymmetric tensors. Like in the matrix case, normalized tensor eigenvectors are fixed points of the tensor power iteration map. Howe…

Newton-type method for bilevel programs with linear lower level problem and application to toll optimization
Floriane Mefo Kue, Thorsten Raasch, Alain B. Zemkoho
We consider a bilevel program involving a linear lower level problem with left-hand-side perturbation. We then consider the Karush-Kuhn-Tucker reformulation of the problem and subs…
