The role of the Beltrami parametrization of complex structures in 2-d Free Conformal Field Theory
Serge Lazzarini
This talk gives a review on how complex geometry and a Lagrangian formulation of 2-d conformal field theory are deeply related. In particular, how the use of the Beltrami parametri…

Flat Complex Vector Bundles, The Beltrami Differential and W-Algebras
S. Lazzarini
Since the appearance of the paper by Bilal & al. in 1991, it has been widely assumed that W-algebras originating from the Hamiltonian reduction of an SL(n,C)-bundle over a Riemann…

Standard model and unimodularity condition
Serge Lazzarini, Thomas Schucker
The unimodularity condition in Connes' formulation of the standard model is rewritten in terms of group representations.
