Lifting -- A nonreversible Markov chain Monte Carlo Algorithm [PDF]

open access: yesarXiv, 2014
Markov chain Monte Carlo algorithms are invaluable tools for exploring stationary properties of physical systems, especially in situations where direct sampling is unfeasible. Common implementations of Monte Carlo algorithms employ reversible Markov chains. Reversible chains obey detailed balance and thus ensure that the system will eventually relax to

On the Vere-Jones classification and existence of maximal measures for countable topological Markov chains [PDF]

open access: yesPacific J. Math., 209, No. 2, 365-380, 2003, 2019
We consider topological Markov chains (also called Markov shifts) on countable graphs. We show that a transient graph can be extended to a recurrent graph of equal entropy which is either positive recurrent of null recurrent, and we give an example of each type.

Anomalous Recurrence Properties of Markov Chains on Manifolds of Negative Curvature [PDF]

open access: yesarXiv, 2020
We present a recurrence-transience classification for discrete-time Markov chains on manifolds with negative curvature. Our classification depends only on geometric quantities associated to the increments of the chain, defined via the Riemannian exponential map.

On Mixing Properties of Reversible Markov Chains [PDF]

open access: yesarXiv, 2014
It is well known that for a strictly stationary, reversible, Harris recurrent Markov chain, the $\rho$-mixing condition is equivalent to geometric ergodicity and to a "spectral gap" condition. In this note, it will be shown with an example that for that class of Markov chains, the "interlaced" variant of the $\rho$-mixing condition fails to be ...

Computable Convergence Rates for Subgeometrically Ergodic Markov Chains [PDF]

open access: yesarXiv, 2005
In this paper, we give quantitative bounds on the $f$-total variation distance from convergence of an Harris recurrent Markov chain on an arbitrary under drift and minorisation conditions implying ergodicity at a sub-geometric rate. These bounds are then specialized to the stochastically monotone case, covering the case where there is no minimal ...

Dependent Discrete Risk Processes - Calculation of the Probability of Ruin

open access: yesOperations Research and Decisions, 2010
This paper is devoted to discrete processes of dependent risks. The random variables describing the time between claims can be dependent in such processes, unlike under the classical approach.

Analyticity of Entropy Rate of Hidden Markov Chains [PDF]

open access: yesarXiv, 2005
We prove that under mild positivity assumptions the entropy rate of a hidden Markov chain varies analytically as a function of the underlying Markov chain parameters. A general principle to determine the domain of analyticity is stated. An example is given to estimate the radius of convergence for the entropy rate.
