Representable presheaves of groups on the homotopy category of cocommutative dg-coalgebras and Tannakian reconstruction
Jaehyeok Lee, Jae-Suk Park
Motivated by rational homotopy theory, we study a representable presheaf of groups on the homotopy category of cocommutative differential graded coalgebras,…
