WebApr 22, 2024 · This textbook is an introduction to the theory of infinity-categories, a tool used in many aspects of modern pure mathematics. It treats the basics of the theory and supplies all the necessary details while leading the reader along a streamlined path from the basic definitions to more advanced results such as the very important adjoint functor … WebPresentable ($\infty$,1)-categories are special among all ($\infty$,1)-categories; in particular, they are complete and cocomplete. For instance, you can define the notion of ($\infty$,1)-topos in terms of model categories, since ($\infty$,1)-topoi are presentable, and morphisms between such are certain kinds of adjoint functor pairs. 7z file extractor online download WebJul 29, 2024 · Let $\mathbf{Cat}$ denote the category of small categories and $\mathbf{MCat}$ the category of small monoidal categories with monoidal functors. … Weband Special Adjoint Functor Theorem [9, 14]. Other well-known adjoint functor theorems include those specialized to locally presentable categories – these can also be regarded as useful non-trivial specializations of Freyd’s theorems.
