Bi-rational maps in four dimensions with two invariants
arXiv:1907.00746 · doi:10.1088/1751-8121/ab72ad
Abstract
In this paper we present a class of four-dimensional bi-rational maps with two invariants satisfying certain constraints on degrees. We discuss the integrability properties of these maps from the point of view of degree growth and Liouville integrability.
