Self-duality and F theory
Sergei V. Ketov
The (2,2) world-sheet supersymmetric string theory is discussed from the viewpoint of string/membrane unification. The effective field theory in the closed string target space is k…
Mixed (open/closed) N=(2,2) string theory as an integrable deformation of self-duality
Sergei V. Ketov
The exact effective field equations of motion, corresponding to the perturbative mixed theory of open and closed (2,2) world-sheet supersymmetric strings, are investigated. It is s…
Solitons, monopoles and duality: from sine-Gordon to Seiberg-Witten
Sergei V. Ketov
An elementary introduction into the Seiberg-Witten theory is given. Many efforts are made to get it as pedagogical as possible, within a reasonable size. The selection of the relev…
Path-Integral Quantization of the (2,2) String
Jan Bischoff, Olaf Lechtenfeld
A complete treatment of the (2,2) NSR string in flat (2+2) dimensional space-time is given, from the formal path integral over N=2 super Riemann surfaces to the computational recip…
Universality of random matrices in the microscopic limit and the Dirac operator spectrum
G. Akemann, P. H. Damgaard, U. Magnea +1
We prove the universality of correlation functions of chiral unitary and unitary ensembles of random matrices in the microscopic limit. The essence of the proof consists in reducin…
The OSp(32|1) versus OSp(8|2) supersymmetric M-brane action from self-dual (2,2) strings
Sergei V. Ketov
Taking the (2,2) strings as a starting point, we discuss the equivalent integrable field theories and analyze their symmetry structure in 2+2 dimensions from the viewpoint of strin…
