internal algebra of symmetry
- an internal symmetry is defined by the algebra of generators
$$ [I_{\alpha},I_{\beta}]=c_{\alpha \beta \gamma}I_{\gamma} $$
- the generators, in turn, are given by the integral over the time-component of the currents
$$ I_{\alpha}=\int d^3x J_{0,\alpha}(x) $$
- from these equations one obtains the equal-time commutation relation of the currents
$$ [J_{0,\alpha}(\mathbf{x}),J_{0,\beta}(\mathbf{y})]=c_{\alpha \beta \gamma} J_{0,\alpha}(\mathbf{x})\delta(\mathbf{x}-\mathbf{y}) $$
