Department of Mathematics and Statistics, University of Calgary, Calgary, Alberta, Canada T2N 1N4

Abstract: The paper describes the topological structure of the maximal ideal space of the algebra of bounded holomorphic functions on a covering of a bordered Riemann surface. Some applications of the obtained results to the theory of bounded operator-valued holomorphic functions on Riemann surfaces are presented.

Keywords: maximal ideal space, interpolating sequence, Blaschke product, Gleason part, analytic disk, covering dimension, cohomology, Freudenthal compactification.
