Salem numbers from a class of star-like trees
Horst Brunotte, Jörg Thuswaldner
We study the Coxeter polynomials associated with certain star-like trees. In particular, we exhibit large Salem factors of these polynomials and give convergence properties of thei…

Periodicity of certain piecewise affine planar maps
Shigeki Akiyama, Horst Brunotte, Attila Petho +1
We determine periodic and aperiodic points of certain piecewise affine maps in the Euclidean plane. Using these maps, we prove for $λ\in\{\frac{\pm1\pm\sqrt5}2,\pm\sqrt2,\pm\sqrt3\…
