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 …

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 …

Conservation laws with nonlocal velocity: the singular limit problem

J Friedrich, S Göttlich, A Keimer, L Pflug - SIAM Journal on Applied …, 2024 - SIAM
We consider conservation laws with nonlocal velocity and show, for nonlocal weights of
exponential type, that the unique solutions converge in a weak or strong sense (dependent …

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 …

Lagrangian-Eulerian approach for nonlocal conservation laws

E Abreu, R De la Cruz, JC Juajibioy… - Journal of Dynamics and …, 2024 - Springer
In this work, we construct and analyze a new fully discrete Lagrangian-Eulerian numerical
method for the treatment of dynamics of conservation laws with nonlocal flux and influence …

On existence and uniqueness of weak solutions to nonlocal conservation laws with BV kernels

GM Coclite, N De Nitti, A Keimer, L Pflug - Zeitschrift für angewandte …, 2022 - Springer
In this note, we extend the known results on the existence and uniqueness of weak solutions
to conservation laws with nonlocal flux. In case the nonlocal term is given by a convolution …

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 …

On the singular limit problem for a discontinuous nonlocal conservation law

A Keimer, L Pflug - Nonlinear Analysis, 2023 - Elsevier
In this contribution, we study the singular limit problem of a nonlocal conservation law with a
discontinuity in space. The corresponding local equation can be transformed …
