On André periods of mixed Tate motives
Ishai Dan-Cohen
In this note, we show that the -adic periods of motives introduced recently by Ancona and FrÄÅ£ilÄ (``André periods'') reduce to the classically studied notion in the case of…
A curve and its abstract generalized Jacobian
Benjamin Castle, Ishai Dan-Cohen, Assaf Hasson
To a smooth proper curve over a field equipped with a -point and an effective divisor coprime to , one may associate the abstract group $J_{\mathfra…
-adic Periods and Selmer Scheme Images
David Corwin, Ishai Dan-Cohen
The Chabauty--Kim method was developed with the aim of approaching effective Faltings', the problem of explicitly determining the finite set of rational points on a hyperbolic curv…
Relative tensor products and Koszul duality in monoidal oo-categories
Ishai Dan-Cohen, Asaf Horev
This semi-expository work covers central aspects of the theory of relative tensor products as developed in Higher Algebra, as well as their application to Koszul duality for algebr…
A motivic Weil height machine for curves
L. Alexander Betts, Ishai Dan-Cohen
The rational points of a smooth curve over a number field map to the set of augmentations of the associated motivic algebra. An expectation, related to Kim's conjecture, is…
