Entropy coincidence conjecture for cluster algebras and periodic Laurent-property maps
Entropy coincidence conjecture for cluster algebras and periodic Laurent-property maps
Let be a cluster algebra, or let be a map with the Laurent property obtained from a cluster algebra with periodicity in the sense of the cited constructions. Let denote algebraic entropy and denote Mahler entropy. Entropy coincidence conjecture. For cluster algebras , and for maps with the Laurent property obtained from cluster algebras with periodicity, the algebraic and Mahler entropies coincide:
This would make Mahler entropy independent of the choice of seed, up to mutation equivalence, and identify it with degree-growth entropy in these settings; the source does not state that the claim has been resolved.
