Sergio Iguri, Mario Castagnino
After an appropriate restatement of the GNS construction for topological -algebras we prove that there exists an isomorphism among the set $\cycl(A)$ of weakly continuous stron…

Coulomb integrals for the SL(2,R) WZNW model
Sergio Iguri, Carmen Nunez
We review the Coulomb gas computation of three-point functions in the SL(2,R) WZNW model and obtain explicit expressions for generic states. These amplitudes have been computed in…

Gauge-fixing Independence of Test Fields in Yang-Mills Theories
Sergio M. Iguri, Francisco D. Mazzitelli
We derive a generalized Nielsen identity for the case of Yang-Mills theories that include some classical fields. We discuss under which circumstances the effective action of the cl…
