Abstract:
Werner Heisenberg proposed noncommutative coordinates as early as 1930 as
a way to avoid divergencies in quantum field theorie. This idea revived in
the last few years, triggered by some mathematical developments that allow
symmetries on such spaces, covariant actions and phenomenological
predictions. These concepts will be introduced and discussed in this
lecture using the theta deformed quantum space as the simplest example.
