Higher category theory is generally regarded as technical and forbidding, but part of it is considerably more tractable: the theory of infinity-categories, higher categories in which all higher morphisms are assumed to be invertible. In "Higher Topos Theory", Jacob Lurie presents the foundations of this theory, using the language of weak Kan complexes introduced by Boardman and...(展开全部)
