We investigate locally compact topological groups for which a generalized
analogue of Heisenberg uncertainty inequality hold. In particular, it is shown
that this inequality holds for Rn×K (where K is a
separable unimodular locally compact group of type I), Euclidean Motion group
and several general classes of nilpotent Lie groups which include thread-like
nilpotent Lie groups, 2-NPC nilpotent Lie groups and several low-dimensional
nilpotent Lie groups
