Selfdecomposable Measures on Simply Connected Nilpotent Groups

  • Riddhi Shah


The concepts of class L measures and selfdecomposable measures are generalised from vector spaces to simply connected nilpotent groups G. It has been shown that any full class L (probability) measure μ on G can be decomposed as μ = μ1* ... *μn, where each μi is a selfdecomposable measure on a subgroup Gi; μ itself is selfdecomposable under certain additional conditions—for example, when μ is symmetric. This generalizes a well known result on vector spaces. Some examples of class L measures on G are also constructed.
