Exact Solutions for Delta‐Shock Wave Interactions in a Magnetohydrodynamics Model

Exact Solutions for Delta‐Shock Wave Interactions in a Magnetohydrodynamics Model

Abstract

ABSTRACT This paper analyzes delta‐shock wave interactions in a one‐dimensional model of magnetohydrodynamics (MHD) described by a nonlinear hyperbolic system of conservation laws. The study is conducted within a distributional framework that generalizes the classical weak solution concept, allowing for Dirac delta‐type initial data. A Cauchy problem formulated as a Riemann problem with singularities in both state variables is solved exactly. The resulting solutions display coherent, soliton‐like dynamics, and a subclass of distributional solitons is identified as a special case of delta‐shock waves. These findings advance the analytical understanding of nonlinear conservation laws with singular data and shed light on novel wave structures in MHD.
