类型与矛盾

Types et contragrédientes

Guy Henniart, Vincent Sécherre

摘要:

设G是p-adic约化群,R是代数闭域.设G在R-向量空间V上的一个光滑表示,G的一个开紧子群K和K的一个光滑不可约表示固定在有限维R-向量空间W上。从W到V的K-同态空间是缠绕代数H(G,K,W)上的右模。我们研究这些结构的行为时,我们通过的contragradient表示的V和W,我们给出的条件下,行为是相同的情况下,复杂的表示。我们采取一种抽象的观点,只利用G的一般性质。在最后一节中,我们将其应用于非阿基米德局部域上的群GL(n)及其内部形式的类型理论。

英文摘要:

Let G be a p-adic reductive group, and R an algebraically closed field. Let us consider a smooth representation of G on an R-vector space V. Fix an open compact subgroup K of G and a smooth irreducible representation of K on a finite-dimensional R-vector space W. The space of K-homomorphisms from W to V is a right module over the intertwining algebra H(G,K,W). We examine how those constructions behave when we pass to the contragredient representations of V and W, and we give conditions under which the behaviour is the same as in the case of complex representations. We take an abstract viewpoint and use only general properties of G. In the last section, we apply this to the theory of types for the group GL(n) and its inner forms over a non-Archimedean local field.
