Unitary Representations and Osterwalder-Schrader Duality
نویسندگان
چکیده
The notions of reflection, symmetry, and positivity from quantum field theory are shown to induce a duality operation for a general class of unitary representations of Lie groups. The semisimple Lie groups which have this c-duality are identified and they are placed in the context of Harish-Chandra’s legacy for the unitary representations program. Our paper begins with a discussion of path space measures, which is the setting where reflection positivity (Osterwalder-Schrader) was first identified as a useful tool of analysis. Le plus court chemin entre deux vérités dans le domaine réel passe par le domaine complexe.

Reflection Positive Stochastic Processes Indexed by Lie Groups
Reflection positivity originates from one of the Osterwalder–Schrader axioms for constructive quantum field theory. It serves as a bridge between euclidean and relativistic quantum field theory. In mathematics, more specifically, in representation theory, it is related to the Cartan duality of symmetric Lie groups (Lie groups with an involution) and results in a transformation of a unitary repr...
متن کاملOsterwalder-Schrader Reconstruction and Diffeomorphism Invariance
The Osterwalder-Schrader reconstruction theorem enables one to obtain a Hilbert space quantum field theory from a measure on the space of (Euclidean) histories of a scalar quantum field. In this note we observe that, in an appropriate setting, this result can be extended to include more general theories. In particular, one can allow gauge fields and consider theories which are invariant under d...
متن کاملA Characterization of Unitary Dualityc)
The concept of unitary duality for topological groups was introduced by H. Chu. All mapping spaces are given the compact-open topology. Let G and H be locally compact groups. G" is the space of continuous finite-dimensional unitary representations of G. Let Horn (C, H") denote the space of all continuous maps from G" to H" which preserve degree, direct sum, tensor product and equivalence. We pr...
متن کاملConstructing Hamiltonian quantum theories from path integrals in a diffeomorphism invariant context
Osterwalder and Schrader introduced a procedure to obtain a (Lorentzian) Hamiltonian quantum theory starting from a measure on the space of (Euclidean) histories of a scalar quantum field. In this paper, we extend that construction to more general theories which do not refer to any background, space-time metric (and in which the space of histories does not admit a natural linear structure). Exa...
متن کاملRealizations of Exceptional U-duality Groups as Conformal and Quasi-conformal Groups and Their Minimal Unitary Representations
We review the novel quasiconformal realizations of exceptional U-duality groups whose ”quantization” lead directly to their minimal unitary irreducible representations. The group E8(8) can be realized as a quasiconformal group in the 57 dimensional charge-entropy space of BPS black hole solutions of maximal N = 8 supergravity in four dimensions and leaves invariant ”lightlike separations” with ...
