19.0 Introduction
The numerical treatment of partial differential equations is, by itself, a vast
subject. Partial differential equations are at ... Recipes dealing with partial differential equations alone. (The
references

provide, of course, available alternatives.)
In most mathematics books, partial differential equations (PDEs) are ... possible choices for
ellipticsecond-order equations, but morecomplicated boundaryconditions
can also be encountered.)
