A description of $A_{\infty }$-weights for VMO

Abstract

We present a new characterization of Muckenhoupt AA_{\infty}-weights whose logarithm is in VMO(R)\operatorname{VMO}(\mathbb{R}) in terms of vanishing Carleson measures on R+2\mathbb{R}_+^2 and vanishing doubling weights on R\mathbb{R}. This also gives a novel description of strongly symmetric homeomorphisms on the real line by using a geometric quantity.
