By uilizing the commution properties of the infinicesimal opcrators, We conserued the ortho-notmal bases of the inrrcucible represenzarions o group, Un expliciely witiout using any knowiedge abous the symmeatic group. Morcover, by using lowering opetators, a simple derivation of the representation of the infinitesimal opesators is aivea

This paper shows that, starting from any conserved current generated by some given infinitesimal symmetry generator, one may use flnite dual transtormations to induce infinitely many inflnitesimal symmetry generators. Thus, besdes starting from ordinary isotopic and space-time translation, this paper also disovers the infinitesimal generators for B

The common index characterizes the whole descent equation.

In accordance with the isospin direetton of some charge operator, we decompose the non-Abelian gauge potential and field strength explicitly and gauge covariantly into "neutral"fields, whose sources are these charges and their dual charges, and "vector particle" fieids which are charged. The deeomposition expressions of SU(N)/U(1)N-I, SU(N)/SU(P) SU(N-P) U(1), SO(N)/SO(N-1) are gives explicitly, including various generalized't Hooft field strength expressions. By separating variables of the equation of motion of the abelianizable gauge field,solution with static dual charge system and retarded solution of linearly accelerated dualcharge have been given.
