Kloosterman sums for prime powers in P-adic fields

Stanley J. Gurak (2009)

Journal de Théorie des Nombres de Bordeaux

Let K be a field of degree n over Q p , the field of rational p -adic numbers, say with residue degree f , ramification index e and differential exponent d . Let O be the ring of integers of K and P its unique prime ideal. The trace and norm maps for K / Q p are denoted T r and N , respectively. Fix q = p r , a power of a prime p , and let η be a numerical character defined modulo q and of order o ( η ) . The character η extends to the ring of p -adic integers p in the natural way; namely η ( u ) = η ( u ˜ ) , where u ˜ denotes the residue class...

Kummer congruences for expressions involving generalized Bernoulli polynomials

Glenn J. Fox (2002)

Journal de théorie des nombres de Bordeaux

We illustrate how a particular expression, involving the generalized Bernoulli polynomials, satisfies systems of congruence relations if and only if a similar expression, involving the generalized Bernoulli numbers, satisfies the same congruence relations. These congruence relations include the Kummer congruences, and recent extensions of the Kummer congruences provided by Gunaratne.

La conjecture de Birch et Swinnerton-Dyer 𝐩 -adique

Pierre Colmez (2002/2003)

Séminaire Bourbaki

La conjecture de Birch et Swinnerton-Dyer prédit que l’ordre r du zéro en s = 1 de la fonction L d’une courbe elliptique E définie sur 𝐐 est égal au rang r du groupe de ses points rationnels. On sait démontrer cette conjecture si r = 0 ou 1 , mais on n’a aucun résultat reliant r et r si r 2 . Nous expliquerons comment Kato démontre que la fonction L p -adique attachée à E a, en s = 1 , un...
