Exponential convergence to quasi-stationary distribution for absorbed one-dimensional diffusions with killing [PDF]
, 2017 This article studies the quasi-stationary behaviour of absorbed one-dimensional diffusion processes with killing on $[0,\infty)$. We obtain criteria for the exponential convergence to a unique quasi-stationary distribution in total variation, uniformly ...

Numerical approximation of a cash-constrained firm value with investment opportunities [PDF]
, 2016 We consider a singular control problem with regime switching that arises in problems of optimal investment decisions of cash-constrained firms. The value function is proved to be the unique viscosity solution of the associated Hamilton-Jacobi-Bellman ...

Domain of attraction of quasi-stationary distribution for one-dimensional diffusions
, 2016 We study quasi-stationarity for one-dimensional diffusions killed at 0, when 0 is a regular boundary and $+\infty$ is an entrance boundary. We give a necessary and sufficient condition for the existence of exactly one quasi-stationary distribution, and ...

Time to a single hybridization event in a group of species with unknown ancestral history
, 2012 We consider a stochastic process for the generation of species which combines a Yule process with a simple model for hybridization between pairs of co-existent species.

The long-run behavior of the stochastic replicator dynamics
, 2005 Fudenberg and Harris' stochastic version of the classical replicator dynamics is considered. The behavior of this diffusion process in the presence of an evolutionarily stable strategy is investigated.

Existence and uniqueness of solution for a fractional hepatitis B model
Computational and Mathematical BiophysicsUnderstanding the dynamics of infectious diseases using mathematical modeling is essential for developing prevention and control measures. Hepatitis B is still a major public health issue in many places, including Kenya, where the high incidence of ...

The exit problem for diffusions with time-periodic drift and stochastic resonance
, 2005 Physical notions of stochastic resonance for potential diffusions in periodically changing double-well potentials such as the spectral power amplification have proved to be defective.
