Higher Topos Theory


# Introduction ## The load to Higher Topos Theory [Leinster] * we might be able to learn The Basics of Category Theory with this book. [Kashiwara / Shapira] Categories and Sheaves * To see Cisinski, the computation of Limits and Kan-extensions are essential. * Computation of Limits / Colimits are worth checking, which might lead to Section 4.2 of HTT [玉木] 広がりゆくトポロジーの世界 * This is a convenient way of seeing the Homotopy Calculus in Japanese [Cisinski] Homotopical Algebra and Higher Categories * Starts with the Theory of Presheaves * The power of Yoneda lemma * Then see the concrete example, simplicial Sets. * The nerve and realization is an adjunction * Over the way, it establishes ∞-category. * The Basics of Model Categories ( Abstraction and the Concrete Examples) ## HTT * Chapter I : Introduction * Chapter II : ∞-categories * Chapter III : ∞-Cat * Chapter IV : ∞-Category Theory (i.e. Limits Computation / Kan Extenstions) * Chapter V : ∞-Topoi * Chapter VI : Higher Topos Theory * Chapter VII : Topology Chapter I-III is the introduction to ∞-Categories
Chapter IV is the Computation Technique ( like in Kashiwara Schapira )
Chapter V, VI is the extension to Topos theory
Chapter VII seems to try How to recapture the topology in terms of HTT
