Decomposition of the Wave Manifold into Lax Admissible Regions and its Application to the Solution of Riemann Problems
Cesar S. Eschenazi, Wanderson J. Lambert, Marlon M. López-Flores +2
We utilize a three-dimensional manifold to solve Riemann Problems that arise from a system of two conservation laws with quadratic flux functions. Points in this manifold represent…

Decomposition of the wave manifold in Lax admissible regions
C. S. Eschenazi, C. F. B. Palmeira
Local solutions of Riemann problems for quadratic systems of two conservation laws were constructed in the geometric context. In this paper, also for quadratic systems, we decompos…
