WebApr 6, 2024 · For cluster algebras of finite type, we identify a canonical "universal" choice of coefficients such that an arbitrary cluster algebra can be obtained from the universal one (of the same type) by ... WebAug 23, 2016 · Cluster algebras and continued fractions. We establish a combinatorial realization of continued fractions as quotients of cardinalities of sets. These sets are sets of perfect matchings of certain graphs, the snake graphs, that appear naturally in the theory of cluster algebras. To a continued fraction $ [a_ {1},a_ {2},\ldots ,a_ {n}]$ we ...
