Branching Processes in a Lévy Random Environment [PDF]
Acta Applicandae Mathematicae, 2017 In this paper, we introduce branching processes in a Lévy random environment. In order to define this class of processes, we study a particular class of non-negative stochastic differential equations driven by Brownian motions and Poisson random measures which are mutually independent.

Random walk with barycentric self-interaction [PDF]
, 2011 We study the asymptotic behaviour of a $d$-dimensional self-interacting random walk $X_n$ ($n = 1,2,...$) which is repelled or attracted by the centre of mass $G_n = n^{-1} \sum_{i=1}^n X_i$ of its previous trajectory. The walk's trajectory $(X_1,...,X_n)

Birth and death processes in interactive random environments
Queueing Systems, 2022 This paper studies birth and death processes in interactive random environments where the birth and death rates and the dynamics of the state of the environment are dependent on each other. Two models of a random environment are considered: a continuous-time Markov chain (finite or countably infinite) and a reflected (jump) diffusion process.

Uncertain Random Optimization Models Based on System Reliability
International Journal of Computational Intelligence Systems, 2020 The reliability of a dynamic system is not constant under uncertain random environments due to the interaction of internal and external factors. The existing researches have shown that some complex systems may suffer from dependent failure processes ...

Random walk in random environment with asymptotically zero perturbation [PDF]
, 2006 We give criteria for ergodicity, transience and null recurrence for the random walk in random environment on \Z+={0,1,2,…}, with reflection at the origin, where the random environment is subject to a vanishing perturbation.

Determining the Economic Manufacturing Lot Size with Expedited Fabrication Rate and Product Quality Assurance [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2020 Operations in manufacturing environments are turbulent. Thus, production managers must be capable of dealing with diverse and unexpected situations, such as either random production of imperfect items or unanticipated changes in customers’ orders ...

The Contact Processes in a Random Environment
The Annals of Probability, 1991 This paper deals with one-dimensional contact process in an i.i.d. environment (CPRE). Let \(\xi_ t\subset\mathbb{Z}\) be the state of the process at time \(t\). Then, the dynamics are formulated as follows: a) Particles are born at unoccupied sites \(x\) at rate \(|\xi_ t\cap\{x- 1, x+1\}|\).

Confounding environmental colour and distribution shape leads to underestimation of population extinction risk. [PDF]
PLoS ONE, 2013 The colour of environmental variability influences the size of population fluctuations when filtered through density dependent dynamics, driving extinction risk through dynamical resonance. Slow fluctuations (low frequencies) dominate in red environments,
