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.

Convergence of clock processes in random environments and ageing in the p-spin SK model [PDF]
, 2010 We derive a general criterion for the convergence of clock processes in random dynamics in random environments that is applicable in cases when correlations are not negligible, extending recent results by Gayrard [(2010), (2011), forthcoming], based on ...

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 ...

Jump-diffusion processes in random environments [PDF]
, 2013 In this paper we investigate jump-diffusion processes in random environments which are given as the weak solutions to SDE's. We formulate conditions ensuring existence and uniqueness in law of solutions. We investigate Markov property.

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 ...

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,

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 \(|\xi_ t\cap\{x- 1, x+1\}|\).

Quenched invariance principles for random walks and elliptic diffusions in random media with boundary [PDF]
, 2014 Via a Dirichlet form extension theorem and making full use of two-sided heat kernel estimates, we establish quenched invariance principles for random walks in random environments with a boundary.
