摘要: Abstract We discuss an application of the method angular quantization to reconstruction form factors local fields in massive integrable models. The general formalism is illustrated with examples Klein-Gordon, sinh-Gordon and Bullough-Dodd For latter two models approach makes it possible obtain free field representations for exponential operators. intriguing relation between deformations Virasoro algebra. deformation associated appears be different from known deformed
