Sufficient and necessary conditions of stochastic permanence and extinction for stochastic logistic populations under regime switching [PDF]
, 2011 In this paper, we prove that a stochastic logistic population under regime switching controlled by a Markov chain is either stochastically permanent or extinctive, and we obtain the sufficient and necessary conditions for stochastic permanence and ...

Dynamics of numerical stochastic perturbation theory [PDF]
, 2018 Numerical Stochastic Perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice quantum field theory. The standard algorithm based on the Langevin equation, however, suffers from several limitations which in ...

The perturbation effect in wildlife systems: an emergent property of simple models [PDF]
, 2012 Population reduction is often used as a control strategy when managing infectious diseases in wildlife populations, however it disrupts existing social structures and increases movement of infectives due to the vacuum effect, which may lead to enhanced ...

Population dynamical behavior of non-autonomous Lotka-Volterra competitive system with random perturbation [PDF]
, 2009 In this paper, we consider a non-autonomous stochastic Lotka-Volterra competitive system dxi(t) = xi(t)[(bi(t)¡ nPj=1aij (t)xj (t))dt+¾i(t)dBi(t)], where Bi(t) (i = 1; 2; ¢ ¢ ¢ ; n) are independent standard Brownian motions. Some dynamical properties are

Polynomial asymptotic stability of damped stochastic differential equations. [PDF]
, 2004 The paper studies the polynomial convergence of solutions of a scalar nonlinear Itˆo stochastic differential equation dX(t) = −f(X(t)) dt + (t) dB(t) where it is known, a priori, that limt!1 X(t) = 0, a.s. The intensity of the stochastic perturbation

An Algebraic Wavenumber Identification (AWI) technique under stochastic conditions
Mechanical systems and signal processing, 2023 This paper presents an inverse Algebraic Wavenumber Identification (AWI) technique for multi-modal 1D-periodic structures, which can extract complex wavenumbers from steady-state vibration measurements under stochastic conditions.

Stochastic E-L Wave Theory: Perturbation Techniques [PDF]
The Journal of the Acoustical Society of America, 1973 Although stochastic E-L (Eulerian-Langrangian) wave theory does not require random perturbation techniques in principle to provide solutions, in practice, ensemble expectations are usually resolved by perturbing the random medium. The fundamental concepts for the evaluation of wave functionals are first treated in one dimension, then a central limit ...
