Polynomial ergodicity of Markov transition kernels

open access: yesStochastic Processes and their Applications, 2003
Let \(\varPhi \) be a time-homogeneous Markov chain on a countably generated measure space \((X,\mathfrak B)\) with a \(\varphi \)-irreducible and aperiodic transition kernel \(P\). Let \(f\geq 1\) be a measurable function on \(X\) and \(r=(r(n))_ {n\geq 1}\) a polynomial sequence, that is, \(\liminf r(n)(n+1)^ {-\beta }>0\), \(\limsup r(n)(n+1 ...

Heavy Tailed Approximate Identities and σ-stable Markov Kernels [PDF]

open access: yesPotential Analysis, 2017
The aim of this paper is to present some results relating the properties of stability, concentration and approximation to the identity of convolution through not necessarily mollification type families of heavy tailed Markov kernels. A particular case is provided by the kernels $K_t$ obtained as the $t$ mollification of $L^{ (t)}$ selected from the ...

Robust Average-Reward Markov Decision Processes [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2023
In robust Markov decision processes (MDPs), the uncertainty in the transition kernel is addressed by finding a policy that optimizes the worst-case performance over an uncertainty set of MDPs.

Weighted Nash Inequalities [PDF]

open access: yes, 2010
Nash or Sobolev inequalities are known to be equivalent to ultracontractive properties of Markov semigroups, hence to uniform bounds on their kernel densities.

Should I stay or should I go? A habitat-dependent dispersal kernel improves prediction of movement. [PDF]

open access: yesPLoS ONE, 2011
The analysis of animal movement within different landscapes may increase our understanding of how landscape features affect the perceptual range of animals.

Evolution and prediction of land use around metro stations

open access: yesFrontiers in Environmental Science, 2023
Metro stations are considered high-quality resources for promoting urban development, which have great influences on the surrounding land use changes. The simulation and prediction of land use change can provide a scientific basis for urban land planning.

The Stochastic Heat Equation Driven by a Gaussian Noise: germ Markov Property [PDF]

open access: yes, 2008
Let $u=\{u(t,x);t \in [0,T], x \in {\mathbb{R}}^{d}\}$ be the process solution of the stochastic heat equation $u_{t}=\Delta u+ \dot F, u(0,\cdot)=0$ driven by a Gaussian noise $\dot F$, which is white in time and has spatial covariance induced by the ...

Derivatives of Markov Kernels and Their Jordan Decomposition [PDF]

open access: yesJournal of Applied Analysis, 2008
Let \((P_\vartheta)_{\vartheta \in \Theta}\) be a parametric family of Markov kernels from a measurable space \((X, \mathcal{X})\) to a locally compact space \(Y\). The family \((P_\vartheta)_{\vartheta \in \Theta}\) is called weakly differentiable at \(\vartheta\) if for any \(x \in X\) there is a finite signed Baire measure \(P'_\vartheta(x, .)\) on \

Sufficient stochastic maximum principle for the optimal control of semi-Markov modulated jump-diffusion with application to Financial optimization [PDF]

open access: yes, 2014
The finite state semi-Markov process is a generalization over the Markov chain in which the sojourn time distribution is any general distribution. In this article we provide a sufficient stochastic maximum principle for the optimal control of a semi ...
