The analytic characterization and modeling of seismic wave propagation using ray theory based formulations is a core aspect of seismology with a distinguished and very important history. Fundamentals of Seismic Wave Propagation, by Chris Chapman, provides a mathematically rigorous and substantially complete summary of theory and techniques, with exercises, written at an accessible level for intermediate-to-advanced seismology graduate students and for the general research community. I was particularly pleased to see that much relevant mathematics is well summarized in a valuable preliminaries section containing mathematical and physics background material, coupled with four focused mathematical Appendices covering relevant integrals, Fourier transforms, ordinary differential equations, and saddle-point methods. This bodes well for the text as a teaching resource.
