On the asymptotic events of a Markov chain

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2, Issue 4, Page 537-587, 1979., 1979
In this paper we investigate some structure properties of the tail σ‐field and the invariant σ‐field of both homogeneous and nonhomogeneous Markov chains as representations for asymptotic events, descriptions of completely nonatomic and atomic sets and global characterizations of asymptotic σ‐fields.

On a stochastic epidemic SIR model with non-homogeneous population: a toy model for HIV

open access: yesOpen Mathematics
In this paper, we generalise a simple discrete-time stochastic SIR-type model introduced by Tuckwell and Williams. The SIR model by Tuckwell and Williams assumes a homogeneous population, a fixed infectious period, and a strict transition from ...

The CLT Analogue for Cyclic Urns

open access: yes, 2015
A cyclic urn is an urn model for balls of types $0,\ldots,m-1$ where in each draw the ball drawn, say of type $j$, is returned to the urn together with a new ball of type $j+1 \mod m$. The case $m=2$ is the well-known Friedman urn. The composition vector,

Optimal minimax strategy in a dice game [PDF]

open access: yes, 2009
Each of two players, by turns, rolls a dice several times accumulating the successive scores until he decides to stop, or he rolls an ace. When stopping, the accumulated turn score is added to the player account and the dice is given to his opponent.

Uniform estimates of nonlinear spectral gaps [PDF]

open access: yes, 2015
By generalizing the path method, we show that nonlinear spectral gaps of a finite connected graph are uniformly bounded from below by a positive constant which is independent of the target metric space. We apply our result to an $r$-ball $T_{d,r}$ in the

Existence of stationary distributions for a class of nonlinear time series models in random environment domain

open access: yesJournal of Inequalities and Applications, 2011
In this paper, we study the problem of a variety of nonlinear time series model Xn+1 = F(Xn, en+1(Zn+1)) in which {Zn+1} is a Markov chain with finite state space, and for every state i of the Markov chain, {en(i)} is a sequence of independent and ...
