FORM-FACTORS AND CORRELATION-FUNCTIONS OF THE STRESS-ENERGY TENSOR INMASSIVE DEFORMATION OF THE MINIMAL MODELS (E(N))(1)CIRCLE-TIMES(E(N))(1) (E(N))(2)/

The magnetic deformation of the Ising model, and the thermal deformati ons of both the tricritical Ising model and the tricritical Potts mode l, are governed by an algebraic structure based on the Dynkin diagram associated with the exceptional algebras E(n) (respectively for n = 8, 7, 6). We make use of these underlying structures as well as the disc rete symmetries of the models to compute the matrix elements of the st ress-energy tensor and its two-point correlation function by means of the spectral representation method.
