Duality in Perturbation Theory
نویسنده
چکیده
Duality is applied to perturbation theory by deriving, given a series solution in a small parameter, the dual one expressed as a series having as a development parameter the inverse of the same parameter considered as large. Clues for a dual simmetry in perturbation theory are given. The method is applied in quantum mechanics to the Rayleigh-Schrödinger perturbation theory and to time-dependent problems showing that dual simmetry is broken in cases where the only meaningful quantities are the transition probabilities.

Duality for vector optimization problems via a general scalarization
Considering a vector optimization problem to which properly efficient solutions are defined by using convex cone-monotone scalarization functions, we attach to it, by means of perturbation theory, new vector duals. When the primal problem, the scalarization function and the perturbation function are particularized, different dual vector problems are obtained, some of them already known in the l...
متن کاملWolfe duality and Mond–Weir duality via perturbations
Considering a general optimization problem, we attach to it by means of perturbation theory two dual problems having in the constraints a subdifferential inclusion relation. When the primal problem and the perturbation function are particularized different new dual problems are obtained. In the special case of a constrained optimization problem, the classical Wolfe and Mond–Weir duals, respecti...

On the Finiteness of N = 8 Quantum Supergravity
We describe the constraints imposed on quantum maximal supergravity theories in perturbation theory by the two duality frameworks: S-duality in superstring theory and the AdS/CFT holographic correspondence between IIB superstring theory and N = 4 super Yang-Mills theory.

متن کاملThe Dual Faces of String
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that, for backgrounds generated from compact WZW and coset models, such duality symmetries are exact to all orders in string perturbation theory. A global treatment of duality symmetries is given, by associating them to the known symmetries of affine current algebras ( affine-Weyl group and exte...
متن کاملDuality Symmetries and Topology Change in String Theory
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that for backgrounds generated from WZW and coset CFT models such duality symmetries are exact to all orders in string perturbation theory. Their implications for string dynamics in non-trivial/singular spacetimes are discussed. CERN-TH.7003/93 September 1993 ∗ Talk given at the EPS 93 Conferenc...
