Abstract

We propose a definition of higher inductive types in (,1)(\infty,1)-categories with finite limits. We show that the (,1)(\infty,1)-category of (,1)(\infty,1)-categories with higher inductive types is finitarily presentable. In particular, the initial (,1)(\infty,1)-category with higher inductive types exists. We prove a form of canonicity: the global section functor for the initial (,1)(\infty,1)-category with higher inductive types preserves higher inductive types.
