摘要翻译：
研究了一类多值齐次函数的极性变换的程度。特别地，我们证明了与齐次多项式$F$相关的极变换的泛型线性空间的前像的阶是由$F$的零轨迹决定的。对于零维-维线性空间，这是Dolgachev的猜想，并由Dimca-Papadima利用拓扑变元证明。我们的方法是代数几何的，依赖于对自然关联的对数叶的高斯映射的研究。

英文摘要：
We investigate the degree of the polar transformations associated to a certain class of multi-valued homogeneous functions. In particular we prove that the degree of the pre-image of generic linear spaces by a polar transformation associated to a homogeneous polynomial $F$ is determined by the zero locus of $F$. For zero dimensional-dimensional linear spaces this was conjecture by Dolgachev and proved by Dimca-Papadima using topological arguments. Our methods are algebro-geometric and rely on the study of the Gauss map of naturally associated logarithmic foliations.
