A proof of Karp's conjecture on the zeros of Toeplitz determinants of rising factorial series
Henry Zweiman
In 2012, D. Karp studied a family of polynomials constructed from Polya frequency sequences and conjectured that all their zeros are real and negative. We prove this conjecture for…

Rational Motions of Minimal Quaternionic Degree with Prescribed Line Trajectories
Zülal Derin Yaqub, Hans-Peter Schröcker
In this paper, we study how to find rational motions that move a line along a given rational ruled surface. Our goal is to find motions with the lowest possible degree using dual q…

Rational Motions of Minimal Quaternionic Degree with Prescribed Plane Trajectories
Zülal Derin Yaqub, Hans-Peter Schröcker
This paper investigates the construction of rational motions of a minimal quaternionic degree that generate a prescribed plane trajectory (a ``rational torse''). Using the algebrai…
