Abstract
The method of Abelian decomposition proposed by Faddeev and Niemi is used to derive the low-energy effective lagrangian of G2 gauge theory. The G2 algebra is studied. The commutation relations among the generators of the G2 algebra are established, based on the framework of its regular maximal subalgebra, an SU(3) algebra.
