%TThe modular group and super-KMS functionals
%XWe show that with every normal, faithful (see below), self-adjoint functional {omega} on a von Neumann algebra A there is associated a canonical one-parameter {sigma}-weakly continuous *- automorphism group {sigma}{sup {omega}} (the analogue of the modular group) and a canonical Z{sub 2} grading {Gamma} on A, commuting with {sigma}{sup {omega}}. The functional {omega} satisfies the weak super-KMS property with respect to {sigma}{sup {omega}} and {Gamma}. Furthermore, {sigma}{sup {omega}} and {Gamma} are unique pair of a {sigma}-weakly continuous one-parameter *-automorphism group and a grading of the algebra, commuting with each other, with respect to which {omega} is weakly super-KMS.
