for which the action is finite and stationary under variations, without assuming any additional boundary conditions at infinity. An element of the proof is the vanishing of the stress tensor for a finite action solution, which actually holds true for the general O(N) o-model. For the two-dimensional

โฆ Synopsis
Quantum matrices in two dimensions, admitting left and right quantum spaces, are classified: they fall mto two famdies, the 2-parametric family GLp.q(2) and a 1-parametric family GLS(2). Phenomena previously found for GLp,q(2) hold in this general situation: (a) powers of quantum matrices are again quantum and (b) entries of the logarithm of a two-dimensional quantum matrix form a Lie algebra AMS subject classification (1991). 16A24.
