Ihara’s Question/oda–matsumoto Conjecture
نویسنده
چکیده
In this manuscript we show that function fields K|k with td(K|k) > dim(k)+1 can be recovered from their maximal pro-` abelian-by-central Galois theory, where dim(k) is the Kronecker dimension. This extends the main result of Pop [P5] beyond the case where k is an algebraic closure of a finite field. We also show how this implies the pro-` form of Ihara’s question / Oda-Matsumoto conjecture I/OM, which implies the classical I/OM.

Weighted completion of Galois groups and Galois actions on the fundamental group
Fix a prime number l. In this paper we prove a conjecture [16, p. 300], which Ihara attributes to Deligne, about the action of the absolute Galois group on the pro-l completion of the fundamental group of the thrice punctured projective line. It is stated below. Similar techniques are also used to prove part of a conjecture of Goncharov [11, Conj. 2.1], also about the action of the absolute Gal...
متن کاملWeighted Completion of Galois Groups and Some Conjectures of Deligne
Fix a prime number l. In this paper we prove l-adic versions of two related conjectures of Deligne, [4, 8.2, p. 163] and [4, 8.9.5, p. 168], concerning mixed Tate motives over the punctured spectrum of the ring of integers of a number field. We also prove a conjecture [11, p. 300], which Ihara attributes to Deligne, about the action of the absolute Galois group on the pro-l completion of the fu...

متن کاملTowards an analogue of Ihara’s lemma for Shimura curves
The object of this work is to present the status of art of an open problem: to provide an analogue for Shimura curves of the Ihara’s lemma [14] which holds for modular curves. We will describe our direct result towards the “Problem of Ihara”and we will present some possible approaches to it, giving a formulation of our conjecture in terms of congruence subgroup problem for quaternion algebras. ...
متن کاملA note on Fouquet-Vanherpe’s question and Fulkerson conjecture
The excessive index of a bridgeless cubic graph $G$ is the least integer $k$, such that $G$ can be covered by $k$ perfect matchings. An equivalent form of Fulkerson conjecture (due to Berge) is that every bridgeless cubic graph has excessive index at most five. Clearly, Petersen graph is a cyclically 4-edge-connected snark with excessive index at least 5, so Fouquet and Vanherpe as...
