Degenerate elliptic resonances
Guido Gentile Giovanni Gallavotti
Quasi-periodic motions on invariant tori of an integrable system of dimension smaller than half the phase space dimension may continue to exists after small perturbations. The para…
Fluctuation theorem revisited
Giovanni Gallavotti
Recently the ``Fluctuation theorem'' has been criticized and incorrect incorrect contents have been atributed to it. Here I reestablish and comment the original statements.
Comments on "On the application of the Gallavotti--Cohen fluctuation relation to thermostatted steady states near equilibrium"
Giovanni Gallavotti
The various versions of cond-mat/0312353 discuss results obtained by me&coworkers in the last decade. I have received requests to comment on the paper and the comments are collecte…
Lyapunov spectra and nonequilibrium ensembles equivalence in 2D fluid mechanics
Giovanni Gallavotti, Lamberto Rondoni, Enrico Segre
We perform numerical experiments to study the Lyapunov spectra of dynamical systems associated with the Navier--Stokes (NS) equation in two spatial dimensions truncated over the Fo…
An experimental test of the local fluctuation theorem in chains of weakly interacting Anosov systems
Giovanni Gallavotti, Fabio Perroni
An experimental test of a large fluctuation theorem is performed on a chain of coupled ``cat maps''. Our interest is focused on the behavior of a subsystem of this chain. A local e…
Ergodic and chaotic hypotheses: nonequilibrium ensembles in statistical mechanics and turbulence
Giovanni Gallavotti
The ergodic hypothesis outgrew from the ancient conception of motion as periodic or quasi periodic. It did cause a revision of our views of motion, particularly through Boltzmann a…
