摘要: In this talk I discuss the form factor approach used to compute correlation functions of integrable models in two dimensions. The Sinh-Gordon model is our basic example. Using Watson’s and recursive equations satisfied by matrix elements local operators, present computation factors elementary field O(x)and stress-energy tensor T μν (x)of theory.
