Why Gauges? Gauge symmetries for the classification of the physical states
Franco Strocchi
This note focuses the problem of motivating the use of gauge symmetries (being the identity on the observables) from general principles, beyond their practical success, starting fr…

The strong CP problem revisited and solved by the gauge group topology
F. Strocchi
We exploit the non-perturbative result that the angle which defines the vacuum structure is not a -number free parameter, as suggested by the instanton semi-classical appro…

A note on Gauss operators and quantizations of Yang-Mills theories
Bruno Bucciotti, Franco Strocchi
The quantization of Yang-Mills field theories requires the introduction of a gauge fixing which leads to a violation of the Local Gauss Law described by the so-called Gauss operato…
