Lorentz covariance, higher-spin superspaces and self-duality
Chandrashekar Devchand, Jean Nuyts
Lorentz covariant generalisations of the notions of supersymmetry, superspace and self-duality are discussed. The essential idea is to extend standard constructions by allowing tan…
On the Self-Dual Geometry of N=2 Strings
Chandrashekar Devchand, Olaf Lechtenfeld
We discuss the precise relation of the open N=2 string to a self-dual Yang-Mills (SDYM) system in 2+2 dimensions. In particular, we review the description of the string target spac…
Extended Self-Dual Yang-Mills from the N=2 String
Chandrashekar Devchand, Olaf Lechtenfeld
We show that the physical degrees of freedom of the critical open string with N=2 superconformal symmetry on the worldsheet are described by a self-dual Yang-Mills field on a hyper…
Four Dimensional Integrable Theories
Ch. Devchand, V. Ogievetsky
There exist many four dimensional integrable theories. They include self-dual gauge and gravity theories, all their extended supersymmetric generalisations, as well the full (non-s…
