New Edition: <a style='color: #192b6c; text-decoration: none;' href='www.worldscientific.com/worldscibooks/10.1142/10467'>The Geometry of Spherical Space Form Groups (2nd Edition)</a>In this volume, the geometry of spherical space form groups is studied using the eta invariant. The author reviews the analytical properties of the eta invariant of Atiyah-Patodi-Singer and describes how the eta invariant gives rise to torsion invariants in both K-theory and equivariant bordism. The eta
