Gauge-invariant variables, WZW models and (2+1)-dimensional Yang-Mills theory
Abstract
Recent progress in understanding (2+1)-dimensional Yang-Mills (YM2+1) theory via the use of gauge-invariant variables is reviewed. Among other things, we discuss the vacuum wavefunction, an analytic calculation of the string tension and the propagator mass for gluons and its relation to the magnetic mass for YM3+1 at nonzero temperature.
