The homotopical nomenclature stems from the fact that a common approach to such generalizations is via abstract homotopy theoryas in nonabelian algebraic topologyand in particular the theory of closed model categories. Weak factorisation systems via quillwn the small object argument.

The first part will introduce the notion of a model category, discuss some of the main examples such as the categories of topological spaces, chain complexes and simplicial sets and describe the fundamental concepts and results of the theory the homotopy category of a model category, Quillen functors, derived functors, the small object argument, transfer theorems. In retrospective, he considered exactness axioms which he introduced in Tohoku in a context of homological algebra to be homotopicla a kind of reasoning bringing understanding to general spaces, such as topoi.

This idea did not extend to homotopy methods in general setups of course, but it had concrete modelling and calculations for topological spaces in mind. See the history of this page for a list of all contributions to it. By using this site, you agree to the Terms of Use and Privacy Policy.

Homotopical algebra – Daniel G. Quillen – Google Books

Whitehead proposed around homotopial subject of algebraic homotopy theory, to deal with classical homotopy theory of spaces via algebraic models.

For the theory of homotoopical categories we will use mainly Dwyer and Spalinski’s introductory paper [3] and Hovey’s monograph [4]. This site is running on Instiki 0. Idea History Related entries. Additional references will be provided during the course depending on the advanced topics that will be treated. The aim of this course is to give an introduction to the theory of model categories.

Lecture 2 February 5th, You can help Wikipedia by expanding it. The course is divided in two parts. A large part but maybe not all of homological algebra can be subsumed as the derived functor s that make sense in model categories, and at least the categories of chain complexes can be treated via Quillen algebrq structures.
