Torsion and Galois representations |
Abstract |
The absolute Galois group of a number field is a mysterious object, that one can try to understand by means of its representations. It is known that holomorphic cuspidal modular newforms are, in a suitable sense, a source of many p-adic Galois representations. More generally, it is conjectured that also torsion classes in the coherent cohomology of Shimura varieties have attached Galois representations, with prescribed local properties. I will give an introduction to these themes, and present results obtained in collaboration with Matthew Emerton and Liang Xiao toward the conjecture. |
