Stability of Fredholm properties on interpolation scales
Copyright policy )Stability of Fredholm properties on interpolation scales
Après avoir mis en évidence une propriété caractérisant les opérateurs de Fredholm, les auteurs montrent que si un opérateur \(T\) linéaire de \(A_ 1+A_ 2\) dans \(B_ 1+B_ 2\) est de Fredholm dans un espace d'interpolation \((A_ 1,A_ 2)_ \theta\) dans \((B_ 1,B_ 2)_ \theta\) (ou intérpolation réelle) alors il reste de Fredholm dans des intérpolés dont les paramètres restent dans un voisinage de \(\theta\).
