刚性内部形式与同晶
Rigid inner forms vs isocrystals
摘要:
我们比较了定义在p-adic域上的连通约化群的精化局部朗兰兹对应的两种表述--一种涉及具有附加结构的同晶的Kottwitz集B(G),另一种涉及arXiv:1304.3292中引入的上同调集H^1(u -> W,Z -> G)。我们表明,如果任何一个声明是有效的所有连接的约化群,那么是其他。我们还讨论了第二个命题如何依赖于H^1(u -> W,Z -> G)中元素的选择。
英文摘要:
We compare two statements of the refined local Langlands correspondence for connected reductive groups defined over a p-adic field -- one involving Kottwitz's set B(G) of isocrystals with additional structure, and one involving the cohomology set H^1(u -> W,Z -> G) introduced in arXiv:1304.3292. We show that if either statement is valid for all connected reductive groups, then so is the other. We also discuss how the second statement depends on the choice of element of H^1(u -> W,Z -> G).
