p-adic域上的散射和一个迹公式

Scattering on the p-adic field and a trace formula

Jean-Francois Burnol

摘要:

我把Lax-Phillips散射理论的建立应用于非阿基米德局部域。可以选择输出空间和输入空间作为彼此的傅里叶变换。Lax-Phillips理论的关键元素被认为是有意义的,并具有预期的相互关系:散射矩阵S,相互作用空间的投影K,收缩半群Z和时间延迟算子T。散射矩阵是因果的,其解析延拓具有期望的极点和零点,其相位导数是T的(非负)谱函数,这也是对K的核的对角线的限制。压缩半群Z通过迹公式与S(和T)相关。在相互作用空间上引入一个奇-偶分次,可以用一个"超迹“来表示Weil局部显式公式。我也适用于我的方法来评估的痕迹认为康纳斯。

英文摘要:

I apply the set-up of Lax-Phillips Scattering Theory to a non-archimedean local field. It is possible to choose the outgoing space and the incoming space to be Fourier transforms of each other. Key elements of the Lax-Phillips theory are seen to make sense and to have the expected interrelations: the scattering matrix S, the projection K to the interacting space, the contraction semi-group Z and the time delay operator T. The scattering matrix is causal, its analytic continuation has the expected poles and zeros, and its phase derivative is the (non-negative) spectral function of T, which is also the restriction to the diagonal of the kernel of K. The contraction semi-group Z is related to S (and T) through a trace formula. Introducing an odd-even grading on the interacting space allows to express the Weil local explicit formula in terms of a ``supertrace''. I also apply my methods to the evaluation of a trace considered by Connes.
