Asymptotically Good Pseudomodes for Toeplitz Matrices and Wiener-Hopf Operators
Albrecht Böttcher, Sergei M. Grudsky · Birkhäuser Basel eBooks · 2004
We describe the structure of asymptotically good pseudomodes for Toeplitz matrices and their circulant analogues as well as for Wiener-Hopf integral operators and a continuous analogue of banded circulant matrices. The pseudomodes of circulant matrices and their continuous analogues are extended, while those of Toeplitz matrices or Wiener-Hopf operators are typically strongly localized in the endpoints. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
