**Abstract: ** Basic quantum mechanics: the
role of operators. Discrete Berry phase: construction from the Bargmann invariant. The continuous limit.
Geometric aspects, topological invariants, overview of the quantum Hall effect. Applications: Aharonov-Bohm
effect; the modern theory of polarization; current as a Berry phase; dc conductivity
as a topological phase in phase-space.
