Non Local Observables and Confinement in BF Formulation of Yang-Mills Theory
Francesco Fucito, Maurizio Martellini, Mauro Zeni
The vev's of the magnetic order-disorder operators in QCD are found in an explicit calculation using the first order formulation of Yang-Mills theory.
Instanton Calculus and Nonperturbative Relations in N=2 Supersymmetric Gauge Theories
Francesco Fucito, Gabriele Travaglini
Using instanton calculus we check, in the weak coupling region, the nonperturbative relation $$ <\Trϕ^2>=iπ\left(\cf-{a\over 2} {\partial\cf\over\partial a}\right)$$ obtained for a…
The BF Formalism for QCD and Quark Confinement
F. Fucito, M. Martellini, M. Zeni
Using the BF version of pure Yang-Mills, it is possible to find a covariant representation of the 't Hooft magnetic flux operator. In this framework, 't Hooft's pioneering work on…
Open Superstrings
Gianfranco Pradisi
We review the basic principles of the construction of open and unoriented superstring models and analyze some representative examples.
Explicit Construction of Yang-Mills Instantons on ALE Spaces
Massimo Bianchi, Francesco Fucito, Maurizio Martellini +1
We describe the explicit construction of Yang-Mills instantons on ALE spaces, following the work of Kronheimer and Nakajima. For multicenter ALE metrics, we determine the abelian i…
