Abstract
This paper is devoted to a study of the traces of functions from the classes B lp,π or F lp,π on a set A ⊂ ℝn. In the proofs the results of Netrusov[Zap. Nauchn. Semin. LOMI 204, 61–81 (1992)] are essentially used. We consider the following questions:
-
(1)
Under what conditions on a compact set K, K ⊂ ℝn, do the traces on K of functions from B lp θ∩ℂ(ℝn) (or F lp θ∩ℂ(ℝn) fill in the entire space C(K)?
-
(2)
Under what conditions on a Borel set A does the space of traces on A of functions from F lp,π , 0<p≤1, coincide with some quasi-Banach lattice?
-
(3)
What is the description of the space of traces in the latter case? See Theorem 2.1 for an answer to (1) and Theorem 2.2 for an answer to (2) and (3). In the last part of the paper we prove counterparts of Theorems 2.1 and 2.2 for spaces of analytic functions Bibliography: 14 titles.,
