## Abstract

We prove that the Birkhoff map $\Omega$ for KdV constructed on $H^{-1}_0(\mathbb{T})$ can be interpolated between $H^{-1}_0(\mathbb{T})$ and $L^2_0(\mathbb{T})$. In particular, the symplectic phase space $H^{1/2}_0(\mathbb{T})$ can be described in terms of Birkhoff coordinates.

## TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
