Query: Geometry and topology in many-body physics   Some intensive observables of the electronic ground state in condensed matter
have a geometrical or even topological nature. In this Review I present the
geometrical observables whose expression is known in a full many-body
framework, beyond band-structure theory. The formalism allows dealing with the
general case of disordered and/or correlated many-electron systems.
