Lower bounds for unbounded operators and semigroups
- Abstract:
-
Let A be an unbounded operator on a Banach space X. It is sometimes useful to improve the operator A by extending it to an operator B on a larger Banach space Y with smaller spectrum. It would be preferable to do this with some estimates for the resolvent of B, and also to extend bounded operators related to A, for example a semigroup generated by A. When X is a Hilbert space, one may also want Y to be Hilbert space. Results of this type for bounded operators have been given by Arens, Read, M...

Clearance
-
Some thesis volumes scanned as part of the digitisation scheme funded by Dr Leonard Polonsky are currently unavailable due to sensitive material or uncleared third-party copyright content. We are attempting to contact authors whose theses are affected.
Alternative access to the full-text
You may be able to access the full-text directly from the publisher's website using the 'Publisher Copy' link in the 'Links & Downloads' box from a research output's ORA record page. This method may require an institutional or individual subscription to the journal/resource.
