A series of textbooks for a reader working alone, from a first proof to the graduate qualifying exam in mathematics.
Each volume is a book of its own, with its own contents, search and exercises. A reference to another volume links straight to it, and hovering over the link shows the cited result without leaving the page.
Work in progress: these are drafts, rebuilt from the current branches, and chapters appear as they are written.
Reading order
Where to start, and what each volume needs.
Start with F1 and read on to F2; its first three chapters open AN1. F3 builds , , and out of sets; AN1 does not need it, since it starts from the axioms that F3 proves for its (dashed arrow). F3 leads on to F4, which collects the algebra (complex numbers, fields, groups, polynomials) that Linear Algebra uses.
Foundations
Proof, sets and numbers: what every later volume takes for granted, taught from the beginning.
Logic as the grammar of proof, for a reader who has never been asked to write one: derivations, rule by rule, for the connectives and quantifiers; truth tables, soundness and completeness; and the way back from derivations to ordinary mathematical prose.
Sets and functions, relations and orders, induction and recursion, and the sizes of infinite sets, from diagonal arguments to the Schröder–Bernstein theorem.
The number systems built out of sets: from the ZF axioms, and as classes of pairs, divisibility and modular arithmetic, and finally , constructed from Cauchy sequences of rationals and proved to be a complete ordered field.
The algebra the later volumes take for granted: the complex numbers built on , fields including , groups and permutations with the sign, formal polynomials, and polynomials over a field from division with remainder to the fundamental theorem of algebra.
Analysis on the real line, from the axioms of a complete ordered field: sequences and series, limits and continuity, the derivative, the Riemann–Darboux integral and power series, each proved from the least upper bound axiom.
Linear algebra for a reader working alone: vector spaces and linear maps, determinants and canonical forms, inner products and spectral theory, forms and tensors, and on to representations and numerical computation.
