Ergodicity and periodic orbits of $p$-adic $(1,2)$-rational dynamical systems with two fixed points

I. A. Sattarov, E. T. Aliev

We consider $(1,2)$-rational functions given on the field of $p$-adic numbers ${\mathbb{Q}}_p$. In general, such a function has four parameters. We study the case when such a function…
