We study non-flat planar 3-webs with infinitesimal symmetries. Using multi-dimensional Schwarzian derivative we give a criterion for linearization of such webs and present a projective classification thereof. Using this classification we show that the Gronwall conjecture is true for 3-webs admitting infinitesimal symmetries.

Gronwall 猜想 3 美元-具有无穷小对称性的网

我们研究具有无穷小对称性的非平面平面 3 网。使用多维 Schwarzian 导数,我们给出了此类网的线性化标准并提出了其投影分类。使用这种分类,我们表明 Gronwall 猜想对于 3-webs 承认无穷小对称性是正确的。
