This week, we finish our study of the topograph of a quadratic form. This includes the following topics:


 * Covers::State/Solving quadratic Diophantine equations in two variables, Covers::State/Bounding riverbends of a given discriminant, Covers::State/Periodicity along the river.
 * Covers::Def/Equivalence of binary quadratic forms, Covers::State/Existence of wells for definite forms, Covers::State/Bounding wells of a given discriminant, Covers::State/Triangle inequalities, Covers::State/Finiteness of the class number for binary quadratic forms.
