Current Algebra

For instance, in a Non-Abelian Yang-Mills symmetry, where ρ is the charge density,

:

[
ho^a(ec{x}),
ho^b(ec{y})]=if^{ab}_c\delta(ec{x}-ec{y})
ho^c(ec{x})

where f are the structure constants of the Lie algebra. If space is a one dimensional circle, there may exist Central Extension s.
