Reduction of the Abstract Four Block Problem to a Nehari Problem
Joseph A. Ball, Israel Gohberg, M. A. Kaashoek · Birkhäuser Basel eBooks · 1992
The abstract version of the four block extension problem is reduced to an abstract Nehari problem of which the solution may be obtained via the band method. It is also shown that the maximum entropy solution of the four block problem may be obtained in this way from the maximum entropy solution of the associated Nehari problem. 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.
