Abstract

The compactification of five-dimensional N = 2 SUSY Yang-Mills (YM) theory
onto a circle provides a four-dimensional YM model with N = 4 SUSY. This su
persymmetry can be broken down to N = 2 if non-trivial boundary conditions
in the compact dimension, phi(x(5) + R) = e(2 pi i epsilon)phi(x(5)), are i
mposed on half of the fields, This two-parameter (R, epsilon) family of com
pactifications includes as particular limits most of the previously studied
four-dimensional N = 2 SUSY YM models with supermultiplets in the adjoint
representation of the gauge group. The finite-dimensional integrable system
associated to these theories via the Seiberg-Witten construction is the ge
neric elliptic Ruijsenaars-Schneider model. In particular the perturbative
(weak coupling) limit is described by the trigonometric Ruijsenaars-Schneid
er model. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
