复曲面簇上的微分算子与傅里叶变换

Differential operators on toric varieties and Fourier transform

Giovanni Felder, Carlo A. Rossi

摘要:

我们表明,傅里叶变换的Weyl代数有一个几何对应的框架内的环面品种,即它们诱导的扭曲环之间的同构的微分算子的正则环面品种,其球迷是相互关联的一维锥的反射。最简单的一类例子是与这种反射有关的复曲面簇到射影空间。它包括仿射空间中一点的爆破和在研究sl(n+1)的极小轨道时出现的簇的奇点的奇点的分解。

英文摘要:

We show that Fourier transforms on the Weyl algebras have a geometric counterpart in the framework of toric varieties, namely they induce isomorphisms between twisted rings of differential operators on regular toric varieties, whose fans are related to each other by reflections of one-dimensional cones. The simplest class of examples is provided by the toric varieties related by such reflections to projective spaces. It includes the blow-up at a point in affine space and resolution of singularities of varieties appearing in the study of the minimal orbit of sl(n+1).
