Global Well-posedness for the Multi-species Boltzmann Equation with Large Amplitude Initial Data

Gyounghun Ko, Myeong-Su Lee, Sung-Jun Son

This paper establishes the global well-posedness of the multi-species Boltzmann equation with large-amplitude initial data in the periodic domain $T^{3}$ . In contrast to the…

A Theory-guided Weighted $L^{2}$ Loss for solving the BGK model via Physics-informed neural networks

Gyounghun Ko, Sung-Jun Son, Seung Yeon Cho +1

While Physics-Informed Neural Networks offer a promising framework for solving partial differential equations, the standard $L^{2}$ loss formulation is fundamentally insufficient whe…
