Infinite-dimensional algebras, sine brackets, and SU(∞) (original) (raw)

ADS

Abstract

We investigate features of the infinite dimensional algebras we have previously introduced, which involve trigonometric functions in their structure constants. We find a realization for them which leads to a basis-independent formulation. A special family of them, the cyclotomic ones, contain SU( N) as invariant subalgebras. In this basis, it is evident by inspection that the algebra of SU(∞) is equivalent to the centerless algebra of SDiff 0 on two-dimensional manifolds. Gauge theories of SU(∞) are thus simply reformulated in terms of surface coordinates.
