Eric J. Mittemeijerxtend the notion of orbital surfaces. In the Galois theory orbital surfaces, orbital curves and points can be expressed by means of divisors and singularities. These are quite classical objects. The classical language does not work nicely in the general theory of surface coverings. Here we have to iExpand 发表于 2025-3-30 13:02:41
