Integrable boundary conditions for quad equations, open boundary reductions and integrable mappings
TL;DR: In this article, the authors introduce the notion of open boundary reductions as a new means to construct discrete integrable mappings and their invariants, which is an alternative to the well-known periodic reductions.

Periodic Trajectories of Ellipsoidal Billiards in the 3-Dimensional Minkowski Space
TL;DR: In this article, the authors give detailed analysis and description of periodic trajectories of the billiard system within an ellipsoid in the 3-dimensional Minkowski space, taking into account all possibilities for the caustics.

The Geometry of Billiards in Ellipses and their Poncelet Grids
TL;DR: In this article, an analysis of the geometry of billiards in ellipses, based on properties of confocal central conics, is presented, which leads to new insights and invariants.
A three-dimensional generalization of QRT maps
Jaume Alonso,Yuri B.Suris,K. Wei +2 more
TL;DR: In this article , a geometric construction of three-dimensional birational maps that preserve two pencils of quadrics is proposed, where the maps act as compositions of involutions, which, in turn, act along the straight line generators of the quadrics of the first pencil and are defined by the intersections with the intersections of the second pencil.

Integrable Billiards on Pseudo-Euclidean Hyperboloids and Extremal Polynomials
TL;DR: In this article, the authors considered a billiard problem for compact domains bounded by confocal conics on a hyperboloid of one sheet in the Minkowski space and provided periodicity conditions in terms of functional Pell equations and related extremal polynomials.
