Abstract: We discuss two examples when iterations of the noncommutative rational map are given by noncommutative Laurent polynomials. The first example is related to noncommutative triangulation of surfaces. The second example, which leads to a noncommutative version of the Catalan numbers, is related to solutions of determinant-like equations.
The talk is based on joint papers with A. Berenstein from U. of Oregon.
