The Motivic Fundamental Group of the Punctured Projective Line

نویسنده

  • BERTRAND J. GUILLOU
چکیده

We describe a construction of an object associated to the fundamental group of P−{0, 1,∞} in the Bloch-Kriz category of mixed Tate motives. This description involves Massey products of Steinberg symbols in the motivic cohomology of the ground field.

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...

Se p 20 04 The motivic fundamental group of P 1 \ { 0 , 1 , ∞ } and the theorem of Siegel

One of the strong motivations for studying the arithmetic fundamental groups of algebraic varieties comes from the hope that they will provide group-theoretic access to Diophantine geometry. This is most clearly expressed by the so-called 'section conjecture' of Grothendieck: Let F be a number field and let X→Spec(F) be a smooth hyperbolic curve. After some choice of base point, we get an exact...

Weighted 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...

Maximum sum element orders of all proper subgroups of PGL(2, q)

In this paper we show that if q is a power of a prime p , then the projective special linear group PSL(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group PGL(2, q) for q odd and even respectively

Flag-transitive Point-primitive symmetric designs and three dimensional projective special linear groups

The main aim of this article is to study (v,k,λ)-symmetric designs admitting a flag-transitive and point-primitive automorphism group G whose socle is PSL(3,q). We indeed show that the only possible design satisfying these conditions is a Desarguesian projective plane PG(2,q) and G > PSL(3,q).
