A family of linearizable recurrences with the Laurent property

Abstract: We consider a family of non-linear recurrences with the Laurent property. Although these recurrences are not generated by mutations in a cluster algebra, they fit within the broader framework of Laurent phenomenon algebras, as introduced recently by Lam and Pylyavskyy. Furthermore, each member of this family is shown to be linearizable in two different ways, in the sense that its iterates satisfy both a linear relation with constant coefficients and a linear relation with periodic coefficients. Associated mono… Show more

“…and this formula coincides with the trace formula of the (different) monodromy that is given by Veselov, Shabat in [27]. Equation ( 55) is obtained by a corresponding trace formula in Lemma 4.3 of [15] for the product p i=1 T i , where T i = (P L(g i , λ i )P −1 ) T , with P = 0 1 1 0 .…”

“…where the arbitrary parameter b is an integration constant. The latter family of recurrences was referred to as the "Extreme polynomial" in [1], where it was obtained from another set of period 1 seeds in LP algebras, and for b = 0 it was independently found in [30], where it was also shown to be linearizable and have the Laurent property (see [21] for further details). However, the recurrences (16) lie beyond the setting of LP algebras.…”
