Parametric continuity of stationary distributions [PDF]

open access: yesEconomic Theory, 2006
This paper develops a mathematical model for a Markovian for a stationary distribution. The set up and mapping of the model has been developed with theorems and illustrations. Necessary and sufficient conditions are derived for the solution scheme and upper and lower bounds are defined for the existence and uniqueness of the model.

Threshold Analysis of a Stochastic SIRS Epidemic Model with Logistic Birth and Nonlinear Incidence

open access: yesMathematics, 2023
The paper mainly investigates a stochastic SIRS epidemic model with Logistic birth and nonlinear incidence. We obtain a new threshold value (R0m) through the Stratonovich stochastic differential equation, different from the usual basic reproduction ...

The stochastic θ method for stationary distribution of stochastic differential equations with Markovian switching

open access: yesAdvances in Difference Equations, 2020
In this paper, stationary distribution of stochastic differential equations (SDEs) with Markovian switching is approximated by numerical solutions generated by the stochastic θ method.

Stationary Worldline Power Distributions [PDF]

open access: yesInternational Journal of Theoretical Physics, 2019
A worldline with a time-independent spectrum is called stationary. Such worldlines are arguably the most simple motions in physics. Barring the trivially static motion, the non-trivial worldlines are uniformly accelerated. As such, a point charge moving along a stationary worldline will emit constant radiative power.

Dynamic Properties for a Second-Order Stochastic SEIR Model with Infectivity in Incubation Period and Homestead-Isolation of the Susceptible Population

open access: yesFractal and Fractional, 2023
In this article, we analyze a second-order stochastic SEIR epidemic model with latent infectious and susceptible populations isolated at home. Firstly, by putting forward a novel inequality, we provide a criterion for the presence of an ergodic ...

On the Entropy Rate of a Random Walk on t-Designs [PDF]

open access: yesMathematics Interdisciplinary Research, 2020
In this paper, a random walk on  t-designs are considered. We assign a weight to each block and walk randomly on the vertices with a probability proportional to the weight of blocks. This stochastic process is a Markov chain.

Intermittency and infinite variance: the case of integrated supOU processes [PDF]

open access: yes, 2021
SupOU processes are superpositions of Ornstein-Uhlenbeck type processes with a random intensity parameter. They are stationary processes whose marginal distribution and dependence structure can be specified independently.

Stochastic multiplicative processes with reset events [PDF]

open access: yes, 1999
We study a stochastic multiplicative process with reset events. It is shown that the model develops a stationary power-law probability distribution for the relevant variable, whose exponent depends on the model parameters.

The Stationary Behaviour of Fluid Limits of Reversible Processes is Concentrated on Stationary Points [PDF]

open access: yes, 2012
Assume that a stochastic processes can be approximated, when some scale parameter gets large, by a fluid limit (also called "mean field limit", or "hydrodynamic limit").

Batch Stationary Distribution Estimation

open access: yesCoRR, 2020
We consider the problem of approximating the stationary distribution of an ergodic Markov chain given a set of sampled transitions. Classical simulation-based approaches assume access to the underlying process so that trajectories of sufficient length can be gathered to approximate stationary sampling.
