Arazy-Cwikel and Calderón-Mityagin type properties of the couples ,
Sergey V. Astashkin, Michael Cwikel, Per G. Nilsson
We establish Arazy-Cwikel type properties for the family of couples , , and show that is a Calderón-Mityagin couple i…
A quick description for engineering students of distributions (generalized functions) and their Fourier transforms
Michael Cwikel
These brief lecture notes are intended mainly for undergraduate students in engineering or physics or mathematics who have met or will soon be meeting the Dirac delta function and…
Interpolation of weighted Sobolev spaces
Michael Cwikel, Amit Einav
In this work we present a newly developed study of the interpolation of weighted Sobolev spaces by the complex method. We show that in some cases, one can obtain an analogue of the…
An alternative characterization of normed interpolation spaces between and
Michael Cwikel, Per G. Nilsson
Given a constant , we study the following property of a normed sequence space : ===================== If is an element o…
Unions of cubes in , combinatorics in and the John-Nirenberg and John-Strömberg inequalities
Michael Cwikel
Suppose that the -dimensional unit cube is the union of three disjoint "simple" sets , and and that the volumes of and are both greater than half the volu…
Some alternative definitions for the "plus-minus" interpolation spaces of Jaak Peetre
Michael Cwikel
The Peetre "plus-minus" interpolation spaces are defined variously via conditions about the unconditional convergence of certain Banach s…
