Diese Veranstaltung ist Teil der Veranstaltungsreihe „Oberseminar Partielle Differentialgleichungen“.

Zusammenfassung: The seminar concerns a calculus for parameter-dependent pseudodi fferential operators on Rn introduced by Grubb. The specfi c feature of this calculus is the so-called "regularity" of the symbols.  A new characterisation of regularity will be presented and it will be discussed how to extend the concept of parameter-ellipticity from symbols of positive regularity to symbols of vanishing or negative regularity.
