Entry / bridge route

Proofs & Mathematical Writing

Read quantified statements; write direct, contrapositive, contradiction and induction arguments.

Book of Proof — Richard Hammack. Direct open PDF

Compare resources in this subject

Can skip if… / selective review

You can explain the quantifiers in a statement and write these forms of proof without relying on a worked solution.

Mathematical Logic & Computability

Use first-order syntax, semantics, quantifiers and proof systems.

forall x: Calgary — P. D. Magnus, Tim Button, Aaron Thomas-Bolduc and Richard Zach, with contributors. Open online text / archive

Compare resources in this subject

Can skip if… / selective review

You can distinguish validity from derivability and explain the relevant soundness and completeness statements.

Set Theory

Understand orders, cardinality, ordinals and the role of axioms.

Set Theory: An Open Introduction — Tim Button. Open online text / archive

Compare resources in this subject

Can skip if… / selective review

You can distinguish countability, cardinality and order type; forcing-specific preparation is a separate step.

Linear Algebra

Work with vector spaces, bases, linear maps, kernels, rank and eigenvalues.

Linear Algebra — Jim Hefferon. Open online text / archive

Compare resources in this subject

Can skip if… / selective review

You can prove rank–nullity, change bases and distinguish diagonalizable maps from general linear maps.

Abstract Algebra & Galois Theory

Use groups, rings, ideals, quotient constructions and field extensions.

Abstract Algebra: Theory and Applications — Thomas W. Judson. Open online text / archive

Compare resources in this subject

Can skip if… / selective review

You can construct quotient groups and rings correctly and state the assumptions of the isomorphism theorems.

Model Theory

Study structures, elementary equivalence, compactness and types.

Lecture Notes — Model Theory (Math 411) — Anand Pillay. Direct open PDF

Compare resources in this subject

Can skip if… / selective review

You can use compactness and elementary embeddings in examples; stability or classification theory may still need a bridge.

Research reading: additional tools

Choose according to the particular text, not as an obligation to complete every foundation again.
