Vehicular traffic, crowds, and swarms: From kinetic theory and multiscale methods to applications and research perspectives

G Albi, N Bellomo, L Fermo, SY Ha, J Kim… - … Models and Methods …, 2019 - World Scientific
This paper presents a review and critical analysis on the modeling of the dynamics of
vehicular traffic, human crowds and swarms seen as living and, hence, complex systems. It …

A mathematical perspective on transformers

B Geshkovski, C Letrouit, Y Polyanskiy… - arXiv preprint arXiv …, 2023 - arxiv.org
Transformers play a central role in the inner workings of large language models. We
develop a mathematical framework for analyzing Transformers based on their interpretation …

Estimators for time synchronization—survey, analysis, and outlook

H Puttnies, P Danielis, AR Sharif, D Timmermann - IoT, 2020 - mdpi.com
Time (or clock) synchronization is a large and vital field of research, as synchronization is a
precondition for many applications. A few example applications are distributed data …

Quantum-like states on complex synchronized networks

GD Scholes - Proceedings of the Royal Society A, 2024 - royalsocietypublishing.org
Recent work has exposed the idea that interesting quantum-like (QL) probability laws,
including interference effects, can be manifest in classical systems. Here, we propose a …

Synchronization and stability for quantum Kuramoto

L DeVille - Journal of Statistical Physics, 2019 - Springer
We present and analyze a nonabelian version of the Kuramoto system, which we call the
Quantum Kuramoto system. We study the stability of several classes of special solutions to …

Benign landscapes of low-dimensional relaxations for orthogonal synchronization on general graphs

AD McRae, N Boumal - SIAM Journal on Optimization, 2024 - SIAM
Orthogonal group synchronization is the problem of estimating elements from the orthogonal
group given some relative measurements. The least-squares formulation is nonconvex. To …

From the relativistic mixture of gases to the relativistic Cucker–Smale flocking

SY Ha, J Kim, T Ruggeri - Archive for Rational Mechanics and Analysis, 2020 - Springer
We present a relativistic model for a mixture of Euler gases with multiple temperatures. For
the proposed relativistic model, we explicitly determine production terms resulting from the …

Emergent dynamics of a generalized Lohe model on some class of Lie groups

SY Ha, D Ko, SW Ryoo - Journal of Statistical Physics, 2017 - Springer
We introduce a Lohe group which is a new class of matrix Lie groups and present a
continuous dynamical system for the synchronization of group elements in a Lohe group …

Emergent behaviors of Lohe tensor flocks

SY Ha, H Park - Journal of Statistical Physics, 2020 - Springer
We present a new aggregation model on the space of rank-m tensors with the same size,
and study emergent dynamics of the proposed model. Our proposed new aggregation …

[HTML][HTML] The Kuramoto model on a sphere: Explaining its low-dimensional dynamics with group theory and hyperbolic geometry

M Lipton, R Mirollo, SH Strogatz - Chaos: An Interdisciplinary Journal …, 2021 - pubs.aip.org
We study a system of N identical interacting particles moving on the unit sphere in d-
dimensional space. The particles are self-propelled and coupled all to all, and their motion is …
