The de Rham homotopy theory and differential graded category

Abstract: This paper is a generalization of [30]. We develop the de Rham homotopy theory of not necessarily nilpotent spaces. We use two algebraic objects: closed dg-categories and equivariant dg-algebras. We see these two objects correspond in a certain way (Prop.3.3.4, Thm.3.4.5). We prove an equivalence between the homotopy category of schematic homotopy types [22] and a homotopy category of closed dg-categories (Thm.1.0.1). We give a description of homotopy invariants of spaces in terms of minimal models (Thm.1.0.2)… Show more

“…The author does not know which formalism is the most adequate one (perhaps it depends on the purposes). If we consider the fine ‐category ICoh false(Sfalse) to be a categorical invariant of S, then this viewpoint is similar to the idea by Moriya that the Tannakian differential graded category prefixT PL false(Sfalse) (in the sense of loc. cit .)…”

“…Remark There are several formalisms of rational homotopy types and rationalizations of non‐nilpotent topological space: for example, fiberwise rationalizations, schematizations, pro‐algebraic homotopy types, Tannakian differential graded categories (see ). The author does not know which formalism is the most adequate one (perhaps it depends on the purposes).…”

“…Section 6.5), although we do not obtain a reconstruction of a rational homotopy type from the associated fine ∞-category. There have been various works on rational homotopy theory for non-nilpotent spaces, for example, see Bousfield-Kan [8], Brown-Szczarba [9], Gómez-Tato-Halperin-Tanré [22], Toën [55], Pridham [48], and Moriya [46] (cf. Remark 6.23).…”
