在特征为3的域k上,证明了不存在直线数大于112的几何光滑四次曲面SP3。此外,具有112条直线的曲面在射影上等价于费马四次曲面。作为一个关键因素,我们得到了光滑四次曲面上二次曲线相交的线数的特征自由上界。
Over a field k of characteristic 3, we prove that there are no geometrically smooth quartic surfaces SP 3 with more than 112 lines. Moreover, the surface with 112 lines is projectively equivalent overto the Fermat quartic. As a key ingredient, we derive a characteristic free upper bound for the number of lines met by a quadric on a smooth quartic surface.
