Classification of Positive Rational Reflection Maps for the Relativistic Collision Yang--Baxter Map

We classify positive jointly rational parametric reflection maps for the one-dimensional relativistic collision Yang--Baxter map, without imposing a degree or birationality hypothesis. There are exactly three families. Two preserve one of the light-cone momenta and allow an arbit...
