The Science of Proof: Mathematical Reasoning and Its Limitations

This is a book on mathematical logic with an approach through systematic proof. It begins with natural deduction, a formalization of usual mathematical proof. It introduces templates that always produce a proof, if a proof exists. A more systematic account of proof leads to the completeness theorem and the compactness theorem. The compactness theorem is related to non-standard models; the book concludes with examples of how this works.

A course on the Weil conjectures

Notes by Davide Lombardo from a 2019 course by Tamás Szamuely devoted to Deligne's proof of the Riemann Hypothesis for smooth projective varieties over finite fields. Katz's recent proof of the hypersurface case and Esnault's spectacular application of the integrality theorem are also discussed. The course concludes with a brief survey of the main results of 'Weil II'.
