Published in 2018 at "Archives of Computational Methods in Engineering"

DOI: 10.1007/s11831-018-9275-2

Abstract: We study the numerical approximation of partial differential equations with random input data. Such problems arise when the uncertainty of the underlying system is taken into account using a probability setting. The main goal of… read more here.

Published in 2019 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2018.10.038

Abstract: Abstract In this paper, by virtue of Malliavin calculus, we establish a relationship between backward doubly stochastic differential equations with random coefficients and quasilinear stochastic PDEs, and thus extend the well-known nonlinear stochastic Feynman–Kac formula… read more here.

Published in 2019 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2018.10.060

Abstract: Abstract We consider an evolution equation generalising the viscous Burgers equation supplemented by an initial condition which is a homogeneous random field. We develop a non-linear framework enabling us to show the existence and regularity… read more here.

Published in 2021 at "Stochastic Analysis and Applications"

DOI: 10.1080/07362994.2021.1980015

Abstract: Given a random system, a Liouville’s equation is an exact partial differential equation that describes the evolution of the probability density function of the solution. In this article, we derive ... read more here.

Published in 2017 at "Stochastic Models"

DOI: 10.1080/15326349.2017.1375860

Abstract: ABSTRACT The Markov renewal equation is considered in the subcritical case where the matrix of total masses of the Fij has spectral radius strictly less than one, and the asymptotics of the Zi(x) is found… read more here.
