二进制形式的不变量

Invariants of Binary Forms

Vishwanath Krishnamoorthy, Tanush Shaska, Helmut Voelklein

摘要:

在$\mathbb C$上直到6次(和更低次)的二进制形式的基本不变式是由Clebsch和Bolza在19世纪使用复杂的符号计算构造的。伊古萨扩展到代数闭域的任何特点使用困难的技术代数几何。本文给出了一个简单的证明,它适用于特征$p > 5$,并使用了Hilbert(在特征0中)和Mumford,Haboush等人(在正特征中)发展的不变量理论的一些概念。此外,还讨论了二元三次体对的类比。

英文摘要:

Basic invariants of binary forms over $\mathbb C$ up to degree 6 (and lower degrees) were constructed by Clebsch and Bolza in the 19-th century using complicated symbolic calculations. Igusa extended this to algebraically closed fields of any characteristic using difficult techniques of algebraic geometry. In this paper a simple proof is supplied that works in characteristic $p > 5$ and uses some concepts of invariant theory developed by Hilbert (in characteristic 0) and Mumford, Haboush et al. in positive characteristic. Further the analogue for pairs of binary cubics is also treated.
