摘 要: In this talk, we show that global monomials on positive spaces are linearly independent, extending the basic fact that Laurent monomials in a Laurent polynomial ring are linearly independent to a much more general setting. Our approach is based on the study of Newton polytopes of Laurent expansions. Our general results apply to positive spaces arising from cluster algebras. In particular, this yields the linear independence of cluster monomials for cluster algebras.
