متن کاملStochastically Perturbed Allelopathic Phytoplankton Model
In this article we have considered a stochastic delay differential equation model for two species competitive phytoplankton system with allelopathic stimulation. We have extended the deterministic model system to a stochastic delay differential equation model system by incorporating multiplicative white noise terms in the growth equations for both species. We have studied the mean square stabil...

متن کاملLong-time behavior of stochastically perturbed neuronal networks
Our investigation is specially motivated by the stochastic version of a common model of potential spread in a dendritic tree. We do not assume the noise in the junction points to be Markovian. In fact, we allow for long-range dependence in time of the stochastic perturbation. This leads to an abstract formulation in terms of a stochastic diffusion with dynamic boundary conditions, featuring fra...
متن کاملStochastically perturbed flows: Delayed and interrupted evolution
We present analytical expressions for the time-dependent and stationary probability distributions corresponding to a stochastically perturbed onedimensional flow with critical points, in two physically relevant situations: delayed evolution, in which the flow alternates with a quiescent state in which the variate remains frozen at its current value for random intervals of time; and interrupted ...
