论文摘要
在4个变量中的六偏合形式的空间中,长度为18的分解,我们确定并描述了一个封闭的子各种,其中包含所有不可识别的六元。子变量的描述是几何的,但是可以从该算法中得出,该算法可以保证给定形式是可识别的。
In the space of sextic forms in 4 variables with a decomposition of length 18 we determine and describe a closed subvariety which contains all non-identifiable sextics. The description of the subvariety is geometric, but one can derive from that an algorithm which can guarantee that a given form is identifiable.
