A note on various holding probabilities for random lazy random walks on finite groups


  • Hildebrand, Martin


The author previously considered certain lazy random walks on arbitrary finite groups. Given a k-tuple (g1,...,gk) of elements of a finite group, one multiplies the previous position of the walk by gi[var epsilon] where i is uniform on {1,...,k} and [var epsilon] has a given distribution on {1,0,-1}. The previous work gave good bounds if P([var epsilon]=1)=P([var epsilon]=-1)=1/4 and P([var epsilon]=0)=1/2 or if P([var epsilon]=1)=P([var epsilon]=0)=1/2. The current paper develops some elementary comparison techniques which work for other distributions for [var epsilon] such as P([var epsilon]=1)=P([var epsilon]=0)=P([var epsilon]=-1)=1/3.
