where G is the Galois group GaI ( I ) /Q) and F is a finite field of characteristic I > 3. Suppose that p is modular of level N, i.e., that it arises from a weight-2 newform of level dividing N and trivial "Nebentypus character." Then p is an odd representation: the matrix p(c) (where c is a complex conjugation in G) has eigenvalues + 1, 1. Since + 1 and 1 are distinct in F, p is absolutely irreducible and has a model over every subfield of F containing the set trace(p ). We assume that F has… Expand
Multiplicities of p-finite mod p Galois representations in Jo(Np)
Let M > 1 be an integer. Let Jo(M) be the Jacobian Pic~ of the modular curve Xo(M)q. Let TM be the .subring of End(Jo(M)) generated by the Hecke operators Tn with n > 1. Suppose that p is a maximalExpand

which is odd (in the sense that det(c) = −1, where c is complex conjugation), arises from reduction modulo p of the p-adic representation attached to a newform by Deligne (see [3]). In such aExpand
Some local ( at p ) properties of residual
In this talk we are going to discuss some local properties of (mod p) Galois representations at the prime p. Let p be a prime number, N a positive integer prime to p, k an integer and : (Z=NZ) ! F pExpand
Torsion points on J0(N) and Galois representations
Suppose that N is a prime number greater than 19 and that P is a point on the modular curve X0(N) whose image in Jo(N) (under the standard embedding ι: X0(N)→J0(N)) has finite order. In [2],Expand
Maps between Jacobians of Shimura curves and congruence kernels
Let p ≥ 5 be a prime, and℘ a place ofQ above it.We denote byGQ the absolute Galois group Gal(Q/Q). For a finite field k of characteristic p, an absolutely irreducible representation ρ : GQ → GL2(k)Expand
Two-dimensional representations in the arithmetic of modular curves
In the theory of automorphic representations of a reductive algebraic group G over a number field K, it is broadly — but not always — true that irreducible representations occurring in L(GA/GK) occurExpand
IMAGES OF SEMISTABLE GALOIS REPRESENTATIONS
ρ : Gal(Q/Q)→ GL(2,Fp) which are semistable in the sense of [15, §1]. (Recall that ρ is semistable if the determinant of ρ is the mod p cyclotomic character χ, the Serre conductor of ρ is squareExpand
CONGRUENCES BETWEEN MODULAR FORMS, CYCLIC ISOGENIES OF MODULAR ELLIPTIC CURVES, AND INTEGRALITY OF P-ADIC L-FUNCTIONS
Let F be a congruence subgroup of type (Ni, N2) and of level N. We study congruences between weight 2 normalized newforms f and Eisenstein series E on F modulo a prime p above a rational prime p.Expand
Modularity of 2-dimensional Galois representations
Our aim is to explain some recent results on modularity of 2-dimensional potentially Barsotti-Tate Galois representations. That such representations should arise from modular forms is a special caseExpand
IRREDUCIBLE GALOIS REPRESENTATIONS ARISING FROM COMPONENT GROUPS OF JACOBIANS
Much has been written about component groups of Néron models of Jacobians of modular curves. In a variety of contexts, these groups have been shown to be “Eisenstein,” which implies that they can beExpand
