Notes on simplicial homotopy theory
WebThese notes were used by the second author in a course on simplicial homotopy theory given at the CRM in February 2008 in preparation for the advanced courses on simplicial methods in higher categories that followed. They form the rst four chapters of a book on … 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- ...
