Web2. While recently reading V. Srinvas book "Algebraic K-theory", I learned the following (lemma 6.1), which is contained in what Peter says: The category of covering spaces of B C is naturally equivalent to the category of functors F: C → Sets for which F ( f) is an isomorphism for every morphism f in C.

An abelian category is a category satisfying just enough axioms so the snake lemma holds. An axiom (that is sometimes forgotten) is that the canonical map \mathop {\mathrm {Coim}} (f) \to \mathop {\mathrm {Im}} (f) of Lemma 12.3.12 is always an isomorphism.

WebCategories in Sage are modeled on the mathematical idea of category, and are distinct from Python classes, which are a programming construct. In most cases, typing x.category () returns the category to which x belongs. If C is a category and x is any object, C (x) tries to make an object in C from x. Web4.18 Finite limits and colimits.
