H. Lindemann,F. Keller,H. G. Velcovskye operators, both localized in energy, are shown to map a weighted ..-space into a slightly larger weighted ..-space. The scattering operator, localized in energy, is shown to be bounded on all the weighted ..-spaces.

The Role of the Hilbert Transform in 2-Dimensional Aerodynamics, known that the Hilbert transform . plays an important role in various areas of aerodynamics for thin obstacles , and in this note we show, as an application of ., how to define the natural steady flows outside a thin obstacle.
