The authors consider a Schrödinger operator H=−Δ+V(x⃗ ) in dimension two with a quasi-periodic potential V(x⃗ ). They prove that the absolutely continuo

In this paper, the authors study matrix functions of bounded type from the viewpoint of describing an interplay between function theory and operator theory. The
