** Functoriality and the Inverse Galois problem (joint with Michael Larsen and Gordan Savin) **

pdf file We prove that given an even integer n, a prime p, and an integer t, there is a positive integer k divisible by t, such that PSp_n(Fpk) appears as a Galois group over Q. This generalises a result of Gabor Wiese which inspired our work. (to appear in Compositio Mathematica)

** Modularity of Galois representations and motives with good reduction properties **

pdf file These are some musings on motives, automorphic forms and Galois representations suggested by the work below on Serre's conjecture. The material is close to the slides from various talks I gave in Boston and Paris, April--June 2006 on Serre's conjecture which are available at http://www.math.harvard.edu/ev/documents.html. Errata: On page 86, l. 5 and l. 6, delete the phrase ``up to semisimiplification''. (appeared in Journal of Ramanujan Math. Soc.)

** Serre's modularity conjecture (II) (joint with Wintenberger) **

pdf file This provides proofs of the technical results, Theorems 4.1 and 5.1, of the paper below.

** Serre's modularity conjecture (I) (joint with Wintenberger) **

pdf file This is the first part of a work that proves Serre's conjecture for odd conductors.
