There is no escaping the noncommutative 2-torus, at least for the student of noncommutative geometry. It is certainly the most accessible nontrivial example of a noncommutative space, a generalised space whose coordinate algebra is no longer commutative, but it is also, perhaps, the most ubiquitous. In this talk, as time permits, I’ll give a brief, conceptual introduction to the noncommutative 2-torus in three of its many, many guises: generalised orbit space, quantised phase space, and hidden geometry of time-frequency analysis.
