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 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 [278], Chapters I, XII and XIII).
