摘要：

In the present work we study dynamical space-time symmetries in noncommutative relativistic theories by using the minimal canonical extension of the Doplicher, Fredenhagen, and Roberts algebra. Our formalism is constructed in an extended space-time with independent degrees of freedom associated with the object of noncommutativity theta(mu nu). In this framework we consider theories that are invariant under the Poincare group P or under its extension P-', when translations in the extra dimensions are permitted. The Noether's formalism adapted to such extended x+theta space-time is employed.
