Abstract
We are concerned with the convergence of numerical schemes for the initial value problem associated with the Keyfitz–Kranzer system of equations. This system is a toy model for several important models such as in elasticity theory, magnetohydrodynamics, and enhanced oil recovery. In this paper, we prove the convergence of three difference schemes. Two of these schemes are shown to converge to the unique entropy solution. Finally, the convergence is illustrated by several examples.
