论文摘要
本文的目的是为均匀的二次图的图像提供另一个证明,该图像在2014年由Graczyk和Ishi给出了相对于均匀锥体的积极的,该图是在2014年给出的。新证明取决于纯粹的代数方法,而原始的取决于分析参数。这使我们能够给出上一篇论文获得的同质锥基本相对不变的明确公式[J.谎言理论24(2014),1013--1032]没有分析论点。
The aim of this paper is to give another proof to a result on the image of a homogeneous quadratic map which is positive with respect to a homogeneous cone, given by Graczyk and Ishi in 2014. The new proof depends on a purely algebraic method, whereas the original depends on analytic arguments. This enables us to give explicit formulas of the basic relative invariants of homogeneous cones, obtained by the previous paper [J. Lie Theory 24 (2014), 1013--1032] without analytic arguments.
