Notes on limits of Sobolev spaces and the continuity of interpolation scales

M Milman - Transactions of the American Mathematical Society, 2005 - ams.org
We extend lemmas by Bourgain-Brezis-Mironescu (2001), and Maz'ya-Shaposhnikova
(2002), on limits of Sobolev spaces, to the setting of interpolation scales. This is achieved by …

On the stability of the differential process generated by complex interpolation

JMF Castillo, WHG Corrêa, V Ferenczi… - Journal of the Institute …, 2022 - cambridge.org
We study the stability of the differential process of Rochberg and Weiss associated with an
analytic family of Banach spaces obtained using the complex interpolation method for …

Interpolation of compact operators: the multidimensional case

F Cobos, J Peetre - Proceedings of the London Mathematical …, 1991 - Wiley Online Library
We investigate how compact operators behave under J and K interpolation methods for N
spaces and two parameters. First we study those methods: relationship with those already …

Interpolation of 2d Banach Spaces and the Calderón Spaces X(E)

DL Fernandez - Proceedings of the London Mathematical …, 1988 - Wiley Online Library
We show that the equivalence of the K and J methods of interpolation for 2d Banach spaces
holds in the case of the Calderón spaces X (E). Consequently, the reiteration theorem also …

On equivalence of K-and J-methods for (n+ 1)-tuples of Banach spaces

I Asekritova, N Krugljak - Studia Mathematica, 1997 - infona.pl
It is shown that the main results of the theory of real interpolation, ie the equivalence and
reiteration theorems, can be extended from couples to a class of (n+ 1)-tuples of Banach …

Complex interpolation of quasi-Banach spaces with an A-convex containing space

A Bernal, J Cerda - Arkiv för Matematik, 1991 - projecteuclid.org
Complex interpolation of general couples (X0, X1) of quasi-Banach spaces has been
considered by several authors [8],[11],[16]. The first approach was made by Rivi6re in his …
