Summary
The loop algebra, consisting of Laurent polynomials valued in a Lie algebra, admits a non-trivial central extension for each choice of invariant pairing on it. This affine Lie algebra and its cousin, the Virasoro algebra, are foundational objects in representation theory and conformal field theory. A natural question then arises: do there exist multivariable, or higher dimensional, generalizations of the affine algebra?
