Geometrical Aspects of Local Gauge Symmetry
Alexandre Guay
University of Pittsburgh
12:05 pm, 5J52 Posvar Hall

Abstract: Recently, many efforts have been made by philosophers of physics to clarify the nature of the local gauge symmetry. This work is justified because this symmetry, which is at the center of all field theories that model fundamental interaction, is, in many respects, different from the symmetries we usually encounter in physics. In this talk, I will expose some aspects of this symmetry using a geometrical approach, hoping to make clearer its physical status. This work seems to me a nice complement to studies already done using constrained Hamiltonian formalism and other studies analyzing the gauge principle.
