Jun 17, 2009 · The source of all great mathematics is the special case, the con-crete example. It is frequent in mathematics that every instance of a concept of seemingly great generality is in essence the same as a small and concrete special case.1 We begin by describing a rather general framework for the derivation of PDEs
