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.
