Gaussian concentration and uniqueness of equilibrium states in lattice systems
J. -R. Chazottes, J. Moles, F. Redig +1
We consider equilibrium states (that is, shift-invariant Gibbs measures) on the configuration space where and is a finite set. We prove that if an…

Dynamical regimes and finite time behavior in a trapped random walk: a direct iterative approach
Elena Floriani, Ricardo Lima, Edgardo Ugalde
We consider a basic one-dimensional model of diffusion which allows to obtain a diversity of diffusive regimes whose speed depends on the moments of the per-site trapping time. Thi…

Exact scaling in the expansion-modification system
Raúl Salgado-García, Edgardo Ugalde
This work is devoted to the study of the scaling, and the consequent power-law behavior, of the correlation function in a mutation-replication model known as the expansion-modifica…
