Abstract
A canonical basis of global Dirac's observables for Yang-Mills theory with fermions are obtained in a functional space in which Gribov ambiguity is absent and Gauss' laws can be solved exactly. In terms of these observables, one can express the Lagrangian, the Hamiltonian, non-Abelian and topological charges. The problem of the covariantization of these non-local and non-polynomial quantities is solved. From a relativistic presymplectic approach to the localization of the relativistic center-of-mass of the field configuration, a ultraviolet cutoff is deduced.
