Abstract

Dwyer-Kan localization at pairs of quasi-isomorphisms of the category of dg Lie-Rinehart pairs (A,M)(A,M), where AA is a semi-free cdga over a field kk of characteristic zero and MM a cell complex in AA-modules, is shown to be equivalent to that of strong homotopy Lie-Rinehart (SH LR) pairs satisfying the same cofibrancy condition. Latter is a category of fibrant objects. We introduce cofibrations of SH LR pairs, construct factorizations, and prove lifting properties. Applying them, we show uniqueness up to homotopy of certain BV-type resolutions. Restricting to dg LR pairs whose underlying cdga is of finite type, and using a different (co)fibrancy condition, we show that the functor (A,M)A(A,M)\mapsto A is a Cartesian fibration with presentable fibers. The two (co)fibrancy conditions yield equivalent \infty-categories under Dwyer-Kan localization.
