Lower estimates of transition densities and bounds on exponential ergodicity for stochastic PDE's

open access: yes, 2006
A formula for the transition density of a Markov process defined by an infinite-dimensional stochastic equation is given in terms of the Ornstein--Uhlenbeck bridge and a useful lower estimate on the density is provided.

Quantum ergodicity for quantum graphs without back-scattering [PDF]

open access: yes, 2015
We give an estimate of the quantum variance for $d$-regular graphs quantised with boundary scattering matrices that prohibit back-scattering. For families of graphs that are expanders, with few short cycles, our estimate leads to quantum ergodicity for ...

The Dominated Ergodic Estimate for Mean Bounded, Invertible, Positive Operators [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
We characterize those positive linear operators with positive inverse for which the dominated ergodic estimate holds. We also prove that for such operators one has mean and a.e. convergence.

On One Approach to Obtaining Estimates of the Rate of Convergence to the Limiting Regime of Markov Chains

open access: yesMathematics
We revisit the problem of the computation of the limiting characteristics of (in)homogeneous continuous-time Markov chains with the finite state space. In general, it can be performed only numerically.

On power-bounded operators and the pointwise ergodic property [PDF]

open access: yesProceedings of the American Mathematical Society, 1981
Lp(Q, 6, I) --* L4(i2,, , p) has the pointwise ergodic property (p.e.p.) if for every f E L(Q , ,i), [n'-1n-1 Tf](t) is a.e. convergent in Q. It is known that T has the p.e.p. in the following cases: for 1

Lower bounds for generalized upcrossings of ergodic averages

open access: yesIllinois Journal of Mathematics, 2003
The authors obtain lower bounds for generalized upcrossings of ergodic averages of measure-preserving transformations, which (as it is shown in the paper) provides information on the number of spatial oscillations for these averages. Some results for downcrossings are obtained as well.

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

A Potential Reduction Algorithm for Two-person Zero-sum Mean Payoff Stochastic Games [PDF]

open access: yes, 2015
We suggest a new algorithm for two-person zero-sum undiscounted stochastic games focusing on stationary strategies. Given a positive real $\epsilon$, let us call a stochastic game $\epsilon$-ergodic, if its values from any two initial positions differ by

Real bounds, ergodicity and negative Schwarzian for multimodal maps [PDF]

open access: yesJournal of the American Mathematical Society, 2004
We consider smooth multimodal maps which have finitely many non-flat critical points. We prove the existence of real bounds. From this we obtain a new proof for the non-existence of wandering intervals, derive extremely useful improved Koebe principles, show that high iterates have ‘negative Schwarzian derivative’ and give results on ergodic properties
