Abstract By introducing a specific type of perturbation,A, in the Hamiltonian, we define a class of gently perturbed states, ϱβ,A, of a canonical ensemble, ϱβ. The perturbations are chosen so as to preserve a relationship of the form ϱβ,A≦ constant ×ϱβ. Applications in ergodic theory and phase transitions are described.
