چکیده
We study the symplectic reparametrizations that are possible for theories of N = 2 supersymmetric vector multiplets in the presence of a chiral background and discuss some of their consequences. One of them concerns an anomaly arising from a conflict between symplectic covariance and holomorphy.

January 1996APPLICATIONS OF SPECIAL GEOMETRY
We review characteristic features of N = 2 supersymmetric vector mul-tiplets and discuss symplectic reparametrizations and their relevance for monopoles and dyons. We close with an analysis of perturbative corrections to the low-energy effective action of N = 2 heterotic superstring vacua.

متن کامل/ 9707262 Special Geometry in Hypermultiplets
We give a detailed analysis of pairs of vector and hypermultiplet theories with N = 2 supersymmetry in four spacetime dimensions that are related by the (classical) mirror map. The symplectic reparametrizations of the special Kähler space associated with the vector multiplets induce corresponding transformations on the hypermultiplets. We construct the Sp(1)×Sp(n) one-forms in terms of which th...

The spectrum of the QCD Dirac operator and chiral random matrix theory: the threefold way. Abstract We argue that the spectrum of the QCD Dirac operator near zero virtuality can be described by random matrix theory. As in the case of classical random matrix ensembles of Dyson we have three different cases: the chiral orthogonal ensemble (chGOE), the chiral unitary ensemble (chGUE) and the chira...
متن کاملSymplectic structure for elastic and chiral conducting cosmic string models
This article is based on the covariant canonical formalism and corresponding symplectic structure on phase space developed by Witten, Zuckerman and others in the context of field theory. After recalling the basic principles of this procedure, we construct the conserved bilinear symplectic current for generic elastic string models. These models describe current carrying cosmic strings evolving i...
متن کاملLocal Symplectic Invariants for Curves
To the best of our knowledge, the study of the local symplectic invariants of submanifolds of Euclidean space was initiated by Chern and Wang in 1947, [6]. They considered mainly the case of curves and hypersurfaces, and obtained structure equations defining a set of local symplectic differential invariants for these objects. We should explain at this stage that by “symplectic invariants” we me...
