par Fumio SAIRAIJI et Takuya YAMAUCHI Résumé. Soit E une Q-courbe centrale sur un corps polyquadra-tique k. Dans cet article, nous donnons une borne supérieure des diviseurs premiers de l'ordre du sous-groupe de torsion k-rationnel E tors (k) (voir Théorèmes 1.1 et 1.2). La notion de Q-courbe cen-trale est une généralisation de celle de courbe elliptique(More)
Let k be the function field of a curve C over a finite field. Let X be a proper smooth curve over k. Then there exists a regular model X which is proper and flat over C. Assume that the Q-coefficient Gal(k sep /k)-representation H 1 ´ et (X × Spec k Spec k sep , Q) is a direct sum of 2 dimensional irreducible representations. Let C 0 denote the set of(More)
Specific identification of enterohemorrhagic Escherichia coli was achieved using microspheres coated with overoxidized polypyrrole. The microspheres are well dispersed in aqueous media, and they specifically, spontaneously, and efficiently bind E. coli O157:H7 through surface area effects. In addition, we found that light-scattering by a single microsphere(More)
Let A lev 11 be the moduli space of (1, 11)-polarized abelian surfaces with a canonical level structure. Let χ be a primitive character of order 5 with conductor 11. In this paper we construct five endoscopic lifts Πi, 0 i 4 from two elliptic modular forms f ⊗ χ i of weight 2 and g ⊗ χ i of weight 4 with complex multiplication by Q(√ −11) such that Πi ∞(More)
