Geometry of autonomous discrete Painlevé equations related to the Weyl group
Jaume Alonso, Yuri B. Suris
Discrete Painlevé equations are integrable two-dimensional birational maps associated to a family of generalized Halphen surfaces. The latter can be seen either as bl…

Invariant volume form for 3D QRT maps
Jaume Alonso, Yuri B. Suris
Recently, we proposed a three-dimensional generalization of QRT maps. These novel maps can be associated with pairs of pencils of quadrics in . By construction, these…

Discrete Painlevé equations from pencils of quadrics in with branching generators
Jaume Alonso, Yuri B. Suris
In this paper we extend the novel approach to discrete Painlevé equations initiated in our previous work [2]. A classification scheme for discrete Painlevé equations proposed by Sa…
