Topology and Geometry of Intersections of Ellipsoids in R^n

This book gives an overview of research in the topology and geometry of intersections of quadrics in $mathbb{R}^n$, with a focus on intersections of concentric ellipsoids and related spaces. Unifying and organizing material previously spread over many articles, it also contains new results. The first part provides very detailed foundations of a wide-ranging theory that could be useful for future developments. It includes chapters on general intersections of quadrics, operations on them
