The Patrick Moore Practical Astronomy Seriess for partial differential equations with variable coefficients. For example, when the underlying domain is strongly pseudo-convex, one is led to use the concept of the Heisenberg group (and more general structures) as a model for the boundary of the domain in the theory of functions of several comp

The Patrick Moore Practical Astronomy Serieslex variables. Such problems indicate a strong need for structures more general than spaces of functions on Euclidean space. The space domain might, for instance, be most conveniently endowed with a quasi-metric induced by a differential operator or tailored to suit the kernel of a given integral operator (see , Chapters I, XII and XIII).

Multipliers of Fourier Transforms,ablish two-weight estimates involving weight functions which do not necessarily belong to the class A.. It should be noted that the derived conditions are not only sufficient but also necessary for a whole class of multipliers under consideration.
