On the Benjamin-Bona-Mahony regularization of the Korteweg-de Vries equation
Published 18 Jan 2025 in math.AP | (2501.10899v1)
Abstract: The Benjamin-Bona-Mahony equation (BBM) is introduced as a regularization of the Korteweg-de Vries equation (KdV) for long water waves \cite{BBM1972}. In this paper, we establish the convergence from the BBM to the KdV for energy class solutions. As a consequence, employing the conservation laws, we extend the known temporal interval of validity for the BBM regularization.
