The polylog quotient and the Goncharov quotient in computational Chabauty-Kim theory I
David Corwin, Ishai Dan-Cohen
Polylogarithms are those multiple polylogarithms that factor through a certain quotient of the de Rham fundamental group of the thrice punctured line known as the polylogarithmic q…

The polylog quotient and the Goncharov quotient in computational Chabauty-Kim theory II
Ishai Dan-Cohen, David Corwin
Building on work by Dan-Cohen--Wewers, Dan-Cohen [DC], and Brown, we push the computational boundary of our explicit motivic version of Kim's method in the case of the thrice punct…

Morphisms of rational motivic homotopy types
Ishai Dan-Cohen, Tomer Schlank
We investigate several interrelated foundational questions pertaining to the study of motivic dga's of Dan-Cohen--Schlank [8] and Iwanari [13]. In particular, we note that morphism…
