Continuity and growth of free multiplicative convolution semigroups. (English) Zbl 1419.46041
Summary: Let \(\mu \) be a compactly supported probability measure on the positive half-line and let \(\mu ^{\boxtimes t}\) be the free multiplicative convolution semigroup. We show that the support of \(\mu ^{\boxtimes t}\) varies continuously as \(t\) changes. We also obtain the asymptotic length of the support of these measures.
