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…
Freezing Phase Transitions for Lattice Systems and Higher-Dimensional Subshifts
J. -R. Chazottes, T. Kucherenko, A. Quas
Let , where and is a finite set, equipped with the action of the shift map. For a given continuous potential $ϕ: \mathcal{A…
Pathwise guessing in categorical time series with unbounded alphabets
J. -R. Chazottes, S. Gallo, D. Takahashi
The following learning problem arises naturally in various applications: Given a finite sample from a categorical or count time series, can we learn a function of the sample that (…
Sharp asymptotics for the quasi-stationary distribution of birth-and-death processes
J. -R. Chazottes, P. Collet, S. Méléard
We study a general class of birth-and-death processes with state space that describes the size of a population going to extinction with probability one. This class con…
Poincaré inequality for Markov random fields via disagreement percolation
J. -R. Chazottes, F. Redig, F. Völlering
We consider Markov random fields of discrete spins on the lattice $\Zd$. We use a technique of coupling of conditional distributions. If under the coupling the disagreement cluster…
Poisson processes for subsystems of finite type in symbolic dynamics
J. -R. Chazottes, Z. Coelho, P. Collet
Let $Δ\subsetneq\V$ be a proper subset of the vertices $\V$ of the defining graph of an irreducible and aperiodic shift of finite type . Let be the subshift of…
