Large-time behavior of composite waves of viscous shocks for the barotropic Navier-Stokes equations
Sungho Han, Moon-Jin Kang, Jeongho Kim
We study the large-time behavior of the 1D barotropic Navier-Stokes flow perturbed from Riemann data generating a composition of two shock waves with small amplitudes. We prove tha…
Hydrodynamic limits of the nonlinear Schrödinger equation with the Chern-Simons gauge fields
Jeongho Kim, Bora Moon
We present two types of the hydrodynamic limit of the nonlinear Schrödinger-Chern-Simons (SCS) system. We consider two different scalings of the SCS system and show that each SCS s…
Hydrodynamic limit of a coupled Cucker-Smale system with strong and weak internal variable relaxation
Jeongho Kim, David Poyato, Juan Soler
In this paper, we present the hydrodynamic limit of a multiscale system describing the dynamics of two populations of agents with alignment interactions and the effect of an intern…
Hamilton-Jacobi Deep Q-Learning for Deterministic Continuous-Time Systems with Lipschitz Continuous Controls
Jeongho Kim, Jaeuk Shin, Insoon Yang
In this paper, we propose Q-learning algorithms for continuous-time deterministic optimal control problems with Lipschitz continuous controls. Our method is based on a new class of…
Hamilton-Jacobi-Bellman Equations for Maximum Entropy Optimal Control
Jeongho Kim, Insoon Yang
Maximum entropy reinforcement learning (RL) methods have been successfully applied to a range of challenging sequential decision-making and control tasks. However, most of existing…
Multi-Objective Predictive Taxi Dispatch via Network Flow Optimization
Beomjun Kim, Jeongho Kim, Subin Huh +2
In this paper, we discuss a large-scale fleet management problem in a multi-objective setting. We aim to seek a receding horizon taxi dispatch solution that serves as many ride req…
Hamilton-Jacobi-Bellman Equations for Q-Learning in Continuous Time
Jeongho Kim, Insoon Yang
In this paper, we introduce Hamilton-Jacobi-Bellman (HJB) equations for Q-functions in continuous time optimal control problems with Lipschitz continuous controls. The standard Q-f…
Propagation of the mono-kinetic solution in the Cucker-Smale-type kinetic equations
Moon-Jin Kang, Jeongho Kim
In this paper, we study the propagation of the mono-kinetic distribution in the Cucker-Smale-type kinetic equations. More precisely, if the initial distribution is a Dirac mass for…
A kinetic description for the herding behavior in financial market
Hyeong-Ohk Bae, Seung-Yeon Cho, Jeongho Kim +1
As a continuation of the study of the herding model proposed in (Bae et al. in arXiv:1712.01085, 2017), we consider in this paper the derivation of the kinetic version of the herdi…
Cucker-Smale model with a bonding force and a singular interaction kernel
Jeongho Kim, Jan Peszek
We prove the lack of asymptotic collisions between particles following the Cucker-Smale flocking model with a bonding force and its simplification. Moreover, we prove that in the c…
