Cluster algebras and markoff numbers
WebThis matchings model is a combinatorial interpretation of Fomin and Zelevinsky’s cluster algebras of type A. One can derive from the matchings model an enumerative meaning for the Markoff numbers, and prove that the associated Laurent polynomials have positive coefficients as was conjectured (much more generally) by Fomin and Zelevinsky. WebThe cluster and frozen variables would include all matrix entries as well as every 2 2 minor contained in one of the two distinguished submatrices. The total number of frozen …

Webphenomenon: every cluster variable, which a priori is just a rational function in the elements of a given cluster, is in fact a Laurent polynomial with integer coefficients. For instance, in each rank 2 algebra A—b;c–, every cluster variable x m is a Laurent polynomial in x 1 and x 2. As a corollary, if we specialize all elements of some ... WebDetails.
