Summary: We introduce the algebra of functions generated by non-commuting coordinates and construct an isomorphism of this algebra to the usual algebra of functions equipped with a noncommutative \(\diamondsuit\) product. In order to be able to formulate dynamics and do field theory, we have to define derivatives and integration. The construction of non-Abelian gauge theory on noncommutative spaces is based on enveloping algebra-valued gauge fields. The number of independent field components is reduced to the number of gauge fields in a usual gauge theory. This is done with the help of the Seiberg-Witten map.
