Periodic homogenisation for two dimensional generalised parabolic Anderson model

Autor: Chen, Yilin, Fehrman, Benjamin, Xu, Weijun

We consider the periodic homogenisation problem for the generalised parabolic Anderson model on two dimensional torus. We show that, for the renormalisation that respects Wick ordering, the homogenisation and renormalisation procedures commute. The m

Periodic homogenisation of a Lévy-type process with small jumps

Autor: Jian Wang, Nikola Sandrić, Ivana Valentić

In this article, we consider the problem of periodic homogenization of a Feller process generated by a pseudo-differential operator, the so-called Lévy-type process. Under the assumptions that the generator has rapidly periodically oscillating coeff

International audience; The periodic homogenisation method is often used to study the behaviour of heterogeneous media, like fibre enforced composites, soils or tissues. In this present work, the method is applied to derive the homogenised behaviour

Cellular materials have excellent specific properties, which make them attractive for aeronautical applications. However, modelling macroscopic structures including a cellular material is either very costly in terms of computational time if the whole
