一类伽罗瓦表示到GL_2 n的势自同构

Potential automorphy for certain Galois representations to GL_2n

Thomas Barnet-Lamb

摘要:

基于Clozel、Harris、Shepherd-Barron和Taylor的工作,本文证明了在对基域进行适当大的全实扩张后,某些伽罗瓦表示会变得自守。这里的主要创新之处是,结果适用于伽罗瓦表示到GL_{2n},以前的工作处理的表示GSp_n。主要的技术是考虑的上同调的Dwork超曲面,特别是,在自然的群作用下的不变量,这一上同调的其他部分。

英文摘要:

Building upon work of Clozel, Harris, Shepherd-Barron, and Taylor, this paper shows that certain Galois representations become automorphic after one makes a suitably large totally-real extension to the base field. The main innovation here is that the result applies to Galois representations to GL_{2n}, where previous work dealt with representations to GSp_n. The main technique is the consideration of the cohomology the Dwork hypersurface, and in particular, of pieces of this cohomology other than the invariants under the natural group action.
