Category Theory & Homological Algebra

Graduate pure-mathematics seminar notes covering categories, functors, chain complexes and homological algebra — all equations rendered as selectable PDF text in backslash-free LaTeX.

• Categories, functors and natural transformations with hooked/two-headed arrows for monomorphisms and epimorphisms
• Homological algebra: chain complexes, homology, derived functors (Ext and Tor), and the Yoneda embedding
• Lie algebras in fraktur notation (mathfrak{g}, mathfrak{su}(2), mathfrak{sl}(n, CC))
• Publication styling: drawn academic crest, SPECIMEN watermark, MicroQR mark, and vertical EAN-13 ISSN spine in rotated SVG

Features used: Shortcodes, Tables, Columns, SVG, Barcodes, Watermarks, Headers & Footers, Styles
