摘要：

With the aim of including dynamical fermions, the gauge-independent loop representation is extended by the introduction of an open path connecting the fermionic sources. This new P representation is developed together with the algebra of gauge-invariant path-dependent operators for the case of QED in 3 + 1 dimensions. Finally, using a cluster approximation, both the ground-state energy and chiral condensate are computed, showing a satisfactory behavior for the strong-coupling region.
