Entropy coincidence conjecture for cluster algebras and periodic Laurent-property maps

About 5 years old · traced to

Let A{\cal A} be a cluster algebra, or let φ\varphi be a map with the Laurent property obtained from a cluster algebra with periodicity in the sense of the cited constructions. Let E{\cal E} denote algebraic entropy and EM{\cal E}_M denote Mahler entropy. Entropy coincidence conjecture. For cluster algebras A{\cal A}, and for maps φ\varphi with the Laurent property obtained from cluster algebras with periodicity, the algebraic and Mahler entropies coincide:

E=EM.{\cal E}={\cal E}_M.

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.
