Coloured Epidemic Models: Functional Law of Large Numbers and Propagation of Chaos

Kushankur Dutta, Olga Izyumtseva, Wasiur R. KhudaBukhsh +1

In this paper, we study a stochastic Susceptible-Infected-Removed (SIR) model where the infection and the recovery rates depend on individual covariates for susceptibility and infe…

From Individual-Based Stochastic Epidemics to Heterogeneous SIR Equations

Olga Izyumtseva, Wasiur R. KhudaBukhsh, M. Gabriela M. Gomes +1

We develop a stochastic framework for a broad class of heterogeneous SIR epidemic models. In the finite-population construction, each initially susceptible individual is assigned a…

Stochastic Analysis of Entanglement-assisted Quantum Communication Channels

Karim S. Elsayed, Olga Izyumtseva, Wasiur R. KhudaBukhsh +1

We present a queueing model for a quantum communication network consisting of a primary queue and a service queue in which Bell pairs are formed and stored. The Bell pairs are inhe…

Local times of self-intersection and sample path properties of Volterra Gaussian processes

Olga Izyumtseva, Wasiur R. KhudaBukhsh

We study a Volterra Gaussian process of the form where is a Wiener process and is a continuous kernel. In dimension one, we prove a law of the…

Clark formula for local time for one class of Gaussian processes

Andrey Dorogovtsev, Olga Izyumtseva, Georgii Riabov +1

In the article we present chaotic decomposition and analog of the Clark formula for the local time of Gaussian integrators. Since the integral with respect to Gaussian integrator i…

On local time for the solution to a white noise driven heat equation

Olga Izyumtseva

In this article we discuss the existence of local time for a class of Gaussian processes which appears as the solutions to some stochastic evolution equations. We show that on smal…
