The Logarithmic Sobolev Constant of The Lamplighter
The Logarithmic Sobolev Constant The Lamplighter
2010/11/12
We give estimates on the logarithmic Sobolev constant of some finite lamplighter graphs in terms of the spectral gap of the underlying base. Also, we give examples of application.
Recently groups giving rise to irrational l2-Betti numbers have been found.All the examples known so far share a common property: they have one of the lamplighter groups Z/p o Z as a subgroup. In this...
