Grothendieck conjecture
Webthe standard conjectures retain their interest for the theory of motives. The first, the Lefschetz standard conjecture (Grothendieck 1969, §3), states that, for a smooth projective variety V over an algebraically closed field, the operators Λ, rendering commutative the diagrams (0 ≤ r≤ 2n, n= dimV) Hr(V) Ln−r −−−−→ ≈ H2n ... WebGrothendieck-Teichmuller conjecture: the morphism G Q A u t ( T ^) is an isomorphism. Here G Q is the absolute Galois group and T ^ is the category whose objects are the profinite fundamental groupoids T g, n of the moduli stacks M g, n (restricted to certain basepoints, tangential basepoints or special automorphisms curves)

WebApr 13, 2024 · Abstract: A lot of the algebraic and arithmetic information of a curve is contained in its interaction with the Galois group. This draws inspiration from topology, where given a family of curves over a base B, the fundamental group of B acts on the cohomology of the fiber. As an arithmetic analogue, given an algebraic curve C defined … Webof the Grothendieck conjecture (resp.the Hom version of the Grothendieck conjecture; the Grothendieck section conjecture).

In the case where Kis finitely generated over Q, Y is also a hyperbolic curve, and at least one of Xand Y is affine, Question 0.1.1 was affirmatively answered by Tamagawa [13].

In mathematics, the Grothendieck–Katz p-curvature conjecture is a local-global principle for linear ordinary differential equations, related to differential Galois theory and in a loose sense analogous to the result in the Chebotarev density theorem considered as the polynomial case.
