English abstract:
For a given deBranges space H(E) we investigate deBranges sub-
spaces defined in terms of majorants on the real axis: if ! is a non-
negative function on R, we consider the subspace
R!(E) = ClosH(E)
F ∈ H(E) : ∃C > 0 : |E−1F| ≤ C! on R
.
We show that R!(E) is a deBranges subspace, describe all subspaces
of this form, and study the majorants ! such that R!(E) = H(E).
We give a criterion for the existence of positive minimal majorants
and characterize finite-dimensional subspaces of the form R!(E) in
terms of minimal majorants.
