An increasing homeomorphism \(h\) on the real line \(\mathbb{R}\) is said to be strongly symmetric if it can extended a quasiconformal of upper half plane \(\mathbb{U}\) onto itself whose Beltrami coefficient \(\mu\) induces vanishing Carleson measure \(|\mu(z)|^2/y\,dx\,dy\) \(\mathbb{U}\). We will deal with class homeomorphisms and its Teichmüller space, which we call VMO-Teichmüller space. I...
