摘要: This talk is based on the joint work with Peigen Cao and Fan  Qin. After a reminder on cluster algebras (K2 and Poisson), we will  define the valuation pairing on an upper cluster algebra and present its  basic properties. The main part of the talk will be devoted to several  applications conerning d-vectors, exchange pairs, factoriality and  F-polynomials.
