Bounded p-adic L-functions of motives at supersingular primes
[Fonctions L p-adiques bornées des motifs en une place très supersingulière]
Comptes Rendus. Mathématique, Volume 349 (2011) no. 7-8, pp. 365-368.

Dans [17] Pollack (2003) a montré que la fonction L p-adique associée à une forme modulaire f=anqn en une place très supersingulière p (ap=0) est contrôlée par deux fonctions dʼIwasawa et deux semi-logarithmes. Nous énonc˛ons une généralisation conjecturale des résultats de Pollack aux fonctions L p-adiques des motifs. Nous donnons divers exemples (produits symétriques et produits tensoriels de formes modulaires) qui confirment cette conjecture.

Pollack (2003) [17] proved that the p-adic L-function attached to a modular form f=anqn at the most supersingular prime p (i.e. ap=0) is controlled by two Iwasawa functions and by two half-logarithms. We formulate a (conjectural) generalization of this result to p-adic L-functions attached to motives, and give examples confirming our expectation (symmetric powers and tensor products of modular forms).
