Categories and Functorsthe category of all sets is handled using Grothendieck’s Axiom of Universes. Epimorphisms, monomorphisms, and similar concepts are investigated. The concept of “enriched categories” (for example, additive categories) is briefly sketched.作者: antipsychotic 時(shí)間: 2025-3-22 03:20

Sarah Henneberger-Sudjana,Fred Hennebergerescending chain condition is formalized. The axioms of Zermelo–Fraenkel Set Theory with Choice, and the arithmetic of ordinals and cardinals, are reviewed, and Zorn’s Lemma is developed. We end with some thoughts on whether set theory is “real”.作者: Bombast 時(shí)間: 2025-3-23 07:53

Varieties of AlgebrasWe at last formally define the concept of a (set-based) algebra, consider classes of algebras defined by families of identities (varieties), and prove Birkhoff’s . theorem. We devote several pages to Lie algebras. Clonal categories, and Lawvere’s Structure and Semantics functors, are briefly introduced.作者: Flat-Feet 時(shí)間: 2025-3-25 16:29
