Abstract
We give combinatorial formulas for F-polynomials in cluster algebras of classical types in terms of the weighted paths in certain directed graphs. As a consequence we prove the positivity of F-polynomials in cluster algebras of classical types.
Keywords
F-polynomials , Cluster algebras of classical types , Positivity conjecture
