Two-dimensional QCD and instanton contribution
A. Bassetto, L. Griguolo, F. Vian
In these notes Yang-Mills theories in 1+1 dimensions are reviewed. Instantons on a sphere prove to be -in the decompactification limit- the key issue to clarify an old controversy…

Instanton contributions to Wilson loops with general winding number in two dimensions and the spectral density
A. Bassetto, L. Griguolo, F. Vian
The exact expression for Wilson loop averages winding n times on a closed contour is obtained in two dimensions for pure U(N) Yang-Mills theory and, rather surprisingly, it display…

Quantum Field Theories with Symmetries in the Wilsonian Exact Renormalization Group
F. Vian
The purpose of the present thesis is the implementation of symmetries in the Wilsonian Exact Renormalization Group (ERG) approach. After recalling how the ERG can be introduced in…
