Semi-Cartesian squares and the Snake Lemma

Autor:	Raoult, Jean-Claude
Rok vydání:	2017
Předmět:	Mathematics - Category Theory
Druh dokumentu:	Working Paper
Popis:	The well-known snake lemma is proved entirely within category theory, without the help of "points with value in..." \`a la Grothendieck, nor pseudo-elements as in Guglielmetti & Zaganidis. Instead, we define and use consistently semi-cartesian squares, which were promoted by C. Chevalley. Comment: 8 pages, self-contained
