THE p-ADIC CLOSURE OF A SUBGROUP OF RATIONAL POINTS ON A COMMUTATIVE ALGEBRAIC GROUP
نویسنده
چکیده
Let G be a commutative algebraic group over Q. Let Γ be a subgroup of G(Q) contained in the union of the compact subgroups of G(Qp). We formulate a guess for the dimension of the closure of Γ in G(Qp), and show that its correctness for certain tori is equivalent to Leopoldt’s conjecture.

On the p-adic closure of a subgroup of rational points on an Abelian variety
In 2007, B. Poonen (unpublished) studied the p–adic closure of a subgroup of rational points on a commutative algebraic group. More recently, J. Belläıche asked the same question for the special case of Abelian varieties. These problems are p–adic analogues of a question raised earlier by B. Mazur on the density of rational points for the real topology. For a simple Abelian variety over the fie...
متن کاملSome remarks on almost rational torsion points par
Let G be a commutative algebraic group defined over a perfect field k. Let k be an algebraic closure of k and Γk be the Galois group of k over k. Following Ribet ([1], [19], see also [7]), we say a point P ∈ G(k) is almost rational over k if whenever σ, τ ∈ Γk are such that σ(P )+ τ(P ) = 2P , then σ(P ) = τ(P ) = P . We denote the almost rational points of G over k by Gar k . Let Gtors denote ...
متن کامل/7-adic Curvature and a Conjecture of Serre
1. In this note we announce a vanishing theorem for the cohomology of discrete subgroups of p-adic groups. The methods and results bear a striking analogy with the real case (see Matsushima [4]). In particular, we define "p-adic curvature" for the p-adic symmetric spaces of Bruhat-Tits (see [1]). As in the real case, we then reduce the proof of our vanishing theorem to the assertion that the mi...
متن کاملGlobally analytic $p$-adic representations of the pro--$p$--Iwahori subgroup of $GL(2)$ and base change, I : Iwasawa algebras and a base change map
This paper extends to the pro-$p$ Iwahori subgroup of $GL(2)$ over an unramified finite extension of $mathbb{Q}_p$ the presentation of the Iwasawa algebra obtained earlier by the author for the congruence subgroup of level one of $SL(2, mathbb{Z}_p)$. It then describes a natural base change map between the Iwasawa algebras or more correctly, as it turns out, between the global distribut...
متن کاملA NOTE ON THE q-ANALOGUE OF p-ADIC log-GAMMA FUNCTION
Let p be a fixed odd prime number. Throughout this paper Z, Q, Zp, Qp and Cp will respectively denote the ring of rational integers, the field of rational numbers, the ring p-adic rational integers, the field of p-adic rational numbers and the completion of the algebraic closure of Qp. Let vp be the normalized exponential valuation of Cp such that |p|p = p−vp(p) = p−1. If q ∈ Cp, we normally as...
