Frames and n-term approximationPawel Bechler Institute of Applied Mathematics and Mechanics Faculty of Mathematics, Informatics and Mechanics, Warsaw University POLAND given at strobl07 (21.06.07 10:00) id: 604 length: 25min status: accepted type: talk LINK-Presentation: http://www.mimuw.edu.pl/~pbechler/pdf/pb_talk_7.pdf ABSTRACT: In this presentation the properties of n-term frame approximation will be considered in a general setting. Specifically, I would like to consider the question how basis-specific notions like greedy/ quasi greedy / almost-greedy (basis), which describe the behavior of bases with respect to n-term approximation, can be transfered to the world of frames. |
