Local and Global Results on Three Dimensional Rarefaction Waves in Spherical Symmetry

This article reports on research concerning rarefaction waves in a three-dimensional, spherically symmetric context. The focus is on mathematical analysis, likely involving the behavior of these waves under specific conditions. The terms "local" and "global" suggest the study of wave properties over different spatial or temporal scales. The source, ArXiv, indicates this is a pre-print or research paper.
