A Model-Order Reduction Technique for Low Rank Rational Perturbations of Linear Eigenproblems
Large and sparse rational eigenproblems where the rational term is of low rank k arise in vibrations of fluid–solid structures and of plates with elastically attached loads. Exp...

Volumes with piecewise quadratic medial surface transforms: Computation of boundaries and trimmed offsets
MOS surfaces are rational surfaces in R3,1 which provide rational envelopes of the associated two-parameter family of spheres. Moreover, all the offsets admit rational parameteriz...

Computation of the degree of rational maps between curves
The degree of a rational map measures how often the map covers the image variety. In particular, when the rational map is a parametrization, the degree measures how often the para...
