Zero-temperature stochastic Ising model on one-dimensional quasi-transitive graphs
Emilio De Santis
We consider the zero-temperature stochastic Ising process describing spin-flip dynamics on an infinite one-dimensional quasi-transitive graph with finite interact…
Zero-temperature stochastic Ising model on planar quasi-transitive graphs
Emilio De Santis, Leonardo Lelli
We study the zero-temperature stochastic Ising model on some connected planar quasi-transitive graphs, which are invariant under rotation and translation. The initial spin configur…
Load-sharing dependence models and construction of voting situations for any arbitrary ranking schemes
Emilio De Santis, Fabio Spizzichino
In this paper we present a study about minima among random variables, about the context of voting theory, and about paradoxes related with such topics. In the field of reliability…
One-dimensional infinite memory imitation models with noise
Emilio De Santis, Mauro Piccioni
In this paper we study stochastic process indexed by constructed from certain transition kernels depending on the whole past. These kernels prescribe that, at any tim…
Stochastic Ising model with flipping sets of spins and fast decreasing temperature
Roy Cerqueti, Emilio De Santis
This paper deals with the stochastic Ising model with a temperature shrinking to zero as time goes to infinity. A generalization of the Glauber dynamics is considered, on the basis…
Relations Between Stochastic Orderings and generalized Stochastic Precedence
Emilio De Santis, Fabio Fantozzi, Fabio Spizzichino
The concept of "stochastic precedence" between two real-valued random variables has often emerged in different applied frameworks. In this paper we consider a slightly more general…
Perfect simulation of autoregressive models with infinite memory
Emilio De Santis, Mauro Piccioni
In this paper we consider the problem of determining the law of binary stochastic processes from transition kernels depending on the whole past. These kernels are linear in the pas…
Stochastic Comparisons between hitting times for Markov Chains and words' occurrences
Emilio De Santis, Fabio Spizzichino
We develop some sufficient conditions for the stochastic ordering between hitting times, in a fixed state, for two Markov chains. In particular, we focus attention on the so called…
Developments in perfect simulation of Gibbs measures through a new result for the extinction of Galton-Watson-like processes
Emilio De Santis, Andrea Lissandrelli
This paper deals with the problem of perfect sampling from a Gibbs measure with infinite range interactions. We present some sufficient conditions for the extinction of processes w…
A general framework for perfect simulation of long memory processes
Emilio De Santis, Mauro Piccioni
In this paper a general approach for the perfect simulation of a stationary process with at most countable state space is outlined. The process is specified through a kernel, presc…
