Entropy of Self-Gravitating Systems from Holst's Lagrangian (2008)
Fatibene, L., Ferraris, M., Francaviglia, M., Pacchiella, G.
We shall prove here that conservation laws from Holst's Lagrangian, often used in LQG, do not agree with the corresponding conservation laws in standard GR. Nevertheless, these differences vanish...
Covariant Lagrangian Formulation of Chern-Simons and BF Theories (2005)
Borowiec, A., Fatibene, L., Ferraris, M., Francaviglia, M.
We investigate the covariant formulation of Chern-Simons theories in a general odd dimension which can be obtained by introducing a vacuum connection field as a reference. Field equations, Noether...
A covariant formalism for Chern-Simons gravity (2003)
Borowiec, A., Ferraris, M., Francaviglia, M.
Chern--Simons type Lagrangians in $d=3$ dimensions are analyzed from the point of view of their covariance and globality. We use the transgression formula to find out a new fully covariant and global...
Lagrangian Symmetries of Chern-Simons Theories (1998)
Borowiec, A., Ferraris, M., Francaviglia, M.
This paper analyses the Noether symmetries and the corresponding conservation laws for Chern-Simons Lagrangians in dimension $d=3$. In particular, we find an expression for the superpotential of...
