Abstract:
In recent years a novel approach towards the understanding of the behavior of gauge symmetries in the presence of noncommutativity has been introduced under the name of Poisson Gauge Theories. Within this framework several results have been obtained in the case of U(1) gauge symmetry, i.e., Poisson Electrodynamics. Interestingly, the geometric framework emerging from the above-mentioned results appears to be that of symplectic groupoids and symplectic realizations. In this talk I will present this geometric framework and show the relation existing among the different notions of field strengths that have been considered so far. Joint work with P. Vitale and V. Kupriyanov
