A Note on Weyl invariance in gravity and the Wess-Zumino functional
J. Attard, S. Lazzarini
It is shown that the explicit calculation of the Wess-Zumino functional pertaining to the breaking term of the Weyl symmetry for the Einstein-Hilbert action allows to restore the W…
Nucleon spin decomposition and differential geometry
Jordan François, Serge Lazzarini, Thierry Masson
In the last few years, the so-called Chen et al. approach of the nucleon spin decomposition has been widely discussed and elaborated on. In this letter we propose a genuine differe…
Large Chiral Diffeomorphisms on Riemann Surfaces and W-algebras
Giuseppe Bandelloni, Serge Lazzarini
The diffeomorphism action lifted on truncated (chiral) Taylor expansion of a complex scalar field over a Riemann surface is presented in the paper under the name of large diffeomor…
Improved Epstein-Glaser Renormalization II. Lorentz invariant framework
J. M. Gracia-Bondia, S. Lazzarini
The Epstein--Glaser type T-subtraction introduced by one of the authors in a previous paper is extended to the Lorentz invariant framework. The advantage of using our subtraction i…
Induced quantum gravity on a Riemann Surface
G. Bandelloni, S. Lazzarini
Induced quantum gravity dynamics built over a Riemann surface is studied in arbitrary dimension. Local coordinates on the target space are given by means of the Laguerre-Forsyth co…
W-(infinity)-algebras in n complex dimensions and Kodaira-Spencer deformations : a symplectic approach
G. Bandelloni, S. Lazzarini
It is shown that the notion of W_\infty-algebra originally carried out over a (compact) Riemann surface can be extended to n complex dimensional (compact) manifolds within a symple…
