Buy Nike Air Max 1 Cheap Szegö and Schur parameters which in
We consider a Nevanlinna–Pick type interpolation problem for Carathéodory functions, where the values of the function and its derivatives up to certain orders are given at finitely many points of the unit disk. The set of all solutions of this problem is described by means of the orthogonal rational functions which play here a similar role as the orthogonal polynomials on the unit circle in the classical case of the trigonometric moment problem. In particular, we use a connection between Szegö and Schur parameters which in the classical situation Buy Nike Air Max 1 Cheap was discovered by Ja.L. Geronimus. A theory is developed which predicts that liquid surfaces can carry a so-called “surface shear wave.” This type of surface wave is characterized by the fact that the direction of the surface motion is perpendicular to the propagation Buy Nike Air Max 1 Uk direction of the wave (transverse wave), but, in contrast to the capillary and gravity waves, is in the plane of the surface. The wave equations of a plane and a circular surface shear wave are derived and their validity range is indicated. It is found that the wavelength and damping coefficient depend on the complex shear modulus of the liquid surface.
