Intrinsic dynamical shadowing of point vortices and finite time singularities
Xavier Leoncini, Perla El Kettani, Edgardo Ugalde
The trajectories of point vortices after a division using reverse collapse route are studied. In this setting, an unexpected peculiar phenomenon appears, corresponding to the shado…

Gaussian concentration bounds for probabilistic cellular automata
Jean-René Chazottes, Frank Redig, Edgardo Ugalde
We study lattice spin systems and analyze the evolution of Gaussian concentration bounds (GCB) under the action of probabilistic cellular automata (PCA), which serve as discrete-ti…
