• Contractive projections in Paley-Wiener spaces 

      Kulikov, Aleksei; Zlotnikov, Ilia (Peer reviewed; Journal article, 2023)
      Let S1 and S2 be disjoint finite unions of parallelepipeds. We describe necessary and sufficient conditions on the sets S1, S2 and exponents p such that the canonical projection P from PWPS1US2 to PWPS1 is a contraction.
