Joël Cohen

摘要:

设$F$是特征$0$的局部非阿基米德域,$G$是$F$上的非连通约化群.我们将$G^0$表示为恒等式的连通分支,并假设商$G/G^0$是阿贝尔的。对于$f$是$G$上的一个局部常数紧支撑函数,$π$是$G$的一个复光滑表示,我们定义$f$在$π$上的傅里叶变换为$π(f) = \int_{G} f(g) π(g) \, dg$,它是$π$的基础向量空间的一个自同态.我们给出了一个描述的图像的傅立叶变换映射:给定的,每个$π$在一定的家庭诱导表示的PDMATHAMO,一个自同态$φ(π)$的基础向量空间,我们提供了必要和充分条件下,存在一个功能$f$(必然是唯一的),使$π(f) = φ(π)$的所有$π$的家庭。

英文摘要:

Let $F$ be a local non archimedian field of characteristic $0$, and $G$ a non-connected reductive group over $F$. We denote $G^0$ the connected component of the identity and assume the quotient $G/G^0$ is abelian. For $f$ a locally constant compactly supported function on $G$ and $π$ a complex smooth representation of $G$, we define the Fourier transform of $f$ evaluated at $π$ to be $π(f) = \int_{G} f(g) π(g) \, dg$, which is an endomorphism of the underlying vector space of $π$. We give a description of the image of this Fourier transform map : given, for every $π$ in a certain family of induced representations of $G$, an endomorphism $φ(π)$ of the underlying vector space, we provide necessary and sufficient conditions under which there exists a function $f$ (necessarily unique) such that $π(f) = φ(π)$ for all $π$ in the family.
