On the Maslov index of symplectic paths that are not transversal to the Maslov cycle. Semi-Riemannian index theorems in the degenerate case
R. Giambo, P. Piccione, A. Portaluri
We use the notion of generalized signatures at a singularity of a smooth curve of symmetric bilinear forms to determine a formula for the computation of the Maslov index in the cas…

Gravitational collapse of barotropic spherical fluids
Roberto Giambo', Fabio Giannoni, Giulio Magli +1
The gravitational collapse of spherical, barotropic perfect fluids is analyzed here. For the first time, the final state of these systems is studied without resorting to simplifyin…
