An uncertainty principle related to the Euclidean motion group
Jens Gerlach Christensen, Henrik Schlichtkrull
We show that a well known uncertainty principle for functions on the circle can be derived from an uncertainty principle for the Euclidean motion group.

The uncertainty principle for operators determined by Lie groups
Jens Gerlach Christensen
For unbounded operators A,B and C in general, with C closure of [A,B] does not lead to the uncertainty relation ||Au|| ||Bu|| >= |<C u,u> |/2. If A,B and C are part of the generato…
