For a typical example of a complete discrete valuation field of type II in the sense of [12], we determine the graded quotients for all . In the Appendix, we describe the Milnor -groups of a certain local ring by using differential modules, which are related to the theory of syntomic cohomology.
In this paper we consider the prehomogeneous vector space for a pair of simple algebras which are inner forms of the type and the type. We mainly study the non-split cases. The main purpose of this paper is to determine the principal parts of the global zeta functions associated with these spaces when the simple algebras are non-split. We also give a description of the sets of rational orbits of these spaces, which clarifies the expected density theorems arising from the properties of these...
Soit un corps -adique, son groupe de Galois absolu et la valuation sur . Dans sa démonstration du théorème d’Ax-Sen-Tate, Ax montre que si pour un , vérifie pour tout , alors il existe tel que , avec . Ax se pose la question de l’optimalité de la constante , que nous étudions ici. En utilisant l’extension de engendrée par les racines -es d’une uniformisante fixée de , nous déterminons la constante optimale, ainsi que des informations supplémentaires sur les tels que pour...
This paper is a constructive investigation of the relationship between classical modular symbols and overconvergent -adic modular symbols. Specifically, we give a constructive proof of acontrol theorem (Theorem 1.1) due to the second author [19] proving existence and uniqueness of overconvergent eigenliftings of classical modular eigensymbols of non-critical slope. As an application we describe a polynomial-time algorithm for explicit computation of associated -adic -functions in this case. In...
A -adic version of Stark’s Conjecture at is attributed to J.-P. Serre and stated (faultily) in Tate’s book on the Conjecture. Building instead on our previous paper (and work of Rubin) on the complex abelian case, we give a new approach to such a conjecture for real ray-class extensions of totally real number fields. We study the coherence of our -adic conjecture and then formulate some integral refinements, both alone and in combination with its complex analogue. A ‘Weak Combined Refined’ version...
