摘要

-我们给出了一种求解商曲面奇点的方法,该奇点是有限群在两条曲线上的乘积作用的商。在特征零的情况下,奇点通过连续分数来解决,该分数被称为Hirzebruch–Jung去语言化。我们在积极特征案例中开发了该方法,其中特征的平方不划分群的顺序。摘要-我们给出了一种求解曲面奇点商的方法,该奇点商表现为两条曲线上有限群产生的动作的商。在零特征中,奇点通过连续分数(Hirzebruch-Jung解凝)求解。我们在严格正特征的情况下开发该方法,其中特征的平方不划分群的顺序。

Quotient singularities of products of two curves
— We give a method to resolve a quotient surface singularity which arises as the quotient of a product action of a finite group on two curves. In the characteristic zero case, the singularity is resolved by means of a continued fraction, which is known as the Hirzebruch–Jung desingularization. We develop the method in the positive characteristic case where the square of the characteristic does not divide the order of the group. Résumé. — Nous donnons une méthode pour résoudre une singularité quotient de surface qui se présente comme le quotient d’une action produit d’un groupe fini sur deux courbes. En caractéristique nulle, la singularité est résolue au moyen d’une fraction continue (désingularisation de Hirzebruch–Jung). Nous développons la méthode dans le cas de la caractéristique strictement positive où le carré de la caractéristique ne divise pas l’ordre du groupe.

期刊介绍: The Annales de l’Institut Fourier aim at publishing original papers of a high level in all fields of mathematics, either in English or in French. The Editorial Board encourages submission of articles containing an original and important result, or presenting a new proof of a central result in a domain of mathematics. Also, the Annales de l’Institut Fourier being a general purpose journal, highly specialized articles can only be accepted if their exposition makes them accessible to a larger audience.
