Sub- and Super-solutions of a Nonlinear PDE, and Application to a Semilinear SPDE [PDF]
2010 Mathematics Subject Classification: 35R60, 60H15, 74H35.We obtain upper and lower bounds for the explosion time of a semi-linear heat equation on a bounded $d$-dimensional domain, perturbed by white noise. The bounds we get are expressed in terms of

Stochastic stability and instability of rumor model
In this study, we present a stochastic rumor model. The stability of the disease-free equilibrium state and instability of the free equilibrium E0{E}_{0} of stochastic epidemics model are considered with the help of Lyapunov functions.

On large deviations regimes for random media models
We investigate the behavior of probabilities of large deviations above the mean versus large deviations below the mean for random additive functionals in a variety of random media models.

Early warning signs for SPDEs with continuous spectrum
In this work, we study early warning signs for stochastic partial differential equations (SPDEs), where the linearisation around a steady state is characterised by continuous spectrum. The studied warning sign takes the form of qualitative changes in the

A note on intermittency for the fractional heat equation [PDF]
The goal of the present note is to study intermittency properties for the solution to the fractional heat equation with initial condition bounded above and below, where β ∈ (0, 2] and the noise W behaves in time like a fractional Brownian motion of index
