A fundamental challenge in mathematical modelling is to find a model that embodies the
essential underlying physics of a system, while at the same time being simple enough to …

Low-dimensional Galerkin approximations of nonlinear delay differential equations

MD Chekroun, M Ghil, H Liu, S Wang - arXiv preprint arXiv:1509.02945, 2015 - arxiv.org
This article revisits the approximation problem of systems of nonlinear delay differential
equations (DDEs) by a set of ordinary differential equations (ODEs). We work in Hilbert …

An energy balance model of heterogeneous extensive green roofs

ML Vilar, L Tello, A Hidalgo, C Bedoya - Energy and Buildings, 2021 - Elsevier
We study a two-layer energy balance model of an extensive green roof. The model
represents the evolution of the temperature in both the vegetation and the substrate layers …

Galerkin approximations of nonlinear optimal control problems in Hilbert spaces

MD Chekroun, A Kröner, H Liu - arXiv preprint arXiv:1704.00427, 2017 - arxiv.org
Nonlinear optimal control problems in Hilbert spaces are considered for which we derive
approximation theorems for Galerkin approximations. Approximation theorems are available …

Linear Galerkin-Legendre spectral scheme for a degenerate nonlinear and nonlocal parabolic equation arising in climatology

Ł Płociniczak - Applied Numerical Mathematics, 2022 - Elsevier
A special place in climatology is taken by the so-called conceptual climate models. These
relatively simple sets of differential equations can successfully describe single mechanisms …
