Nonlocal balance laws–an overview over recent results

A Keimer, L Pflug - Handbook of Numerical Analysis, 2023 - Elsevier
In this contribution we give a short overview of recent advances in nonlocal conservation
laws. In these equations, we assume that the flux f is decomposable into f (x)= V (x) x, x∈ R …

Nonlocal traffic models with general kernels: singular limit, entropy admissibility, and convergence rate

M Colombo, G Crippa, E Marconi… - Archive for Rational …, 2023 - Springer
Nonlocal conservation laws (the signature feature being that the flux function depends on
the solution through the convolution with a given kernel) are extensively used in the …

A general result on the approximation of local conservation laws by nonlocal conservation laws: The singular limit problem for exponential kernels

GM Coclite, JM Coron, N De Nitti, A Keimer… - Annales de l'Institut …, 2022 - ems.press
We deal with the problem of approximating a scalar conservation law by a conservation law
with nonlocal flux. As convolution kernel in the nonlocal flux, we consider an exponential …

Modeling multilane traffic with moving obstacles by nonlocal balance laws

A Bayen, J Friedrich, A Keimer, L Pflug… - SIAM Journal on Applied …, 2022 - SIAM
We consider a system of nonlocal balance laws where each balance law is coupled with the
remaining balance laws both by a nonlocal velocity function that takes into account the …

Ole\u {\i} nik-type estimates for nonlocal conservation laws and applications to the nonlocal-to-local limit

GM Coclite, M Colombo, G Crippa, N De Nitti… - arXiv preprint arXiv …, 2023 - arxiv.org
We consider a class of nonlocal conservation laws with exponential kernel and prove that
quantities involving the nonlocal term $ W:=\mathbb {1} _ {(-\infty, 0]}(\cdot)\exp …

Long-time convergence of a nonlocal Burgers' equation towards the local N-wave

GM Coclite, N De Nitti, A Keimer, L Pflug, E Zuazua - Nonlinearity, 2023 - iopscience.iop.org
We study the long-time behaviour of the unique weak solution of a nonlocal regularisation of
the (inviscid) Burgers equation where the velocity is approximated by a one-sided …

On the singular limit problem for nonlocal conservation laws: A general approximation result for kernels with fixed support

A Keimer, L Pflug - arXiv preprint arXiv:2310.09041, 2023 - arxiv.org
We prove the convergence of solutions of nonlocal conservation laws to their local entropic
counterpart for a fundamentally extended class of nonlocal kernels when these kernels …

Discontinuous nonlocal conservation laws and related discontinuous ODEs–Existence, Uniqueness, Stability and Regularity

A Keimer, L Pflug - Comptes Rendus …, 2023 - comptes-rendus.academie-sciences …
We study nonlocal conservation laws with a discontinuous flux function of regularity L∞(R)
in the spatial variable and show existence and uniqueness of weak solutions in C ([0, T]; L1 …

A nonlocal Lagrangian traffic flow model and the zero-filter limit

GM Coclite, KH Karlsen, NH Risebro - Zeitschrift für angewandte …, 2024 - Springer
In this study, we start from a Follow-the-Leaders model for traffic flow that is based on a
weighted harmonic mean (in Lagrangian coordinates) of the downstream car density. This …

In this article, we present the convergence analysis of a second-order numerical scheme for
traffic flow models that incorporate non-local conservation laws. We combine a MUSCL-type …
