Notes on simplicial homotopy theory

WebNote that even in the case of simplicial sets it’s difficult to give an ‘intrinsic’ definition of weak equivalence—in general one has to come up with the ‘right’ notions of cofibrant and fibrant, and build the corresponding cofibrant/fibrant- ...

The effective model structure and -groupoid … WebHomology vs. homotopy. Homotopy groups are similar to homology groups in that they can represent "holes" in a topological space. There is a close connection between the first homotopy group () and the first homology group (): the latter is the abelianization of the former. Hence, it is said that "homology is a commutative alternative to homotopy". how do you manually regenerate water softener https://plumsebastian.com
