Interpolation of Subcouples and Quotient Couples
نویسنده
چکیده
We extend recent results by Pisier on K-subcouples, i.e. subcouples of an interpolation couple that preserve the K-functional (up to constants) and corresponding notions for quotient couples. Examples include interpolation (in the pointwise sense) and a reinter-pretation of the Adamyan-Arov-Krein theorem for Hankel operators.

متن کاملInterpolation of Banach Algebras and Tensor Products of Banach Couples
We consider interpolation of unital Banach algebras, in the special case when the intersection space is non-unital, giving precise conditions of when an interpolation algebra is unital.
متن کاملComplemented Subspaces of Spaces Obtained by Interpolation
If Z is a quotient of a subspace of a separable Banach space X, and V is any separable Banach space, then there is a Banach couple (A0, A1) such that A0 and A1 are isometric to X ⊕ V , and any intermediate space obtained using the real or complex interpolation method contains a complemented subspace isomorphic to Z. Thus many properties of Banach spaces, including having non-trivial cotype, hav...
متن کاملChapter 4 A priori error estimates for conforming finite element approximations 4 . 1 Interpolation in
For a simply-connected Lipschitz domain Ω ⊂ lR d and m ∈ lN 0 we consider the quotient space W m+1,p (Ω)/P m (Ω), p ∈ [1, ∞], whose elements are equivalence classes [u] according to [u] := { w ∈ W m+1,p (Ω) | w − u ∈ P m (Ω) }. We recall that W m+1,p (Ω)/P m (Ω) is a Banach space with respect to the Sobolev quotient norm (4.1) [u] m+1,p,Ω := inf p∈P m (Ω) u + p m+1,p,Ω. A basic result states th...

Veronese webs appear as the natural way of passing to the quotient of curves in the projective space. In this paper, we give the link between classical multidimensional webs and Veronese webs by means of interpolation.
