Mirrors and Reflections The Geometry of Finite Reflection Groups – PDF/EPUB Version Downloadable

“Mirrors and Reflections” presents a systematic and elementary introduction to the properties of finite groups generated by reflections. The approach is based on fundamental geometric considerations in Coxeter complexes, and emphasizes the intuitive geometric aspects of the theory of reflection groups. The exposition is directed at advanced undergraduates and first-year graduate students, and features a large number of exercises at various levels of difficulty.
