Fe b 20 08 A characterization of Schur multipliers between character-automorphic Hardy spaces

  title={Fe b 20 08 A characterization of Schur multipliers between character-automorphic Hardy spaces},
  author={Daniel Alpay and Mamadou Mboup},
We give a new characterization of character-automorphic Hardy spaces of order 2 and of their contractive multipliers in terms of de Branges Rovnyak spaces. Keys tools in our arguments are analytic extension and a factorization result for matrix-valued analytic functions due to Leech.
