Abstract | |||||||||||||||
| Given a squarefree polynomial P 2 k 0 [x; y], k 0 a number eld, we construct a linear dierential operator that allows one to calculate the genus of the complex curve dened by P = 0 (when P is absolutely irreducible), the absolute factorization of P over the algebraic closure of k 0, and calculate information concerning the Galois group of P over k 0 (x) as well as over k 0 (x). | |||||||||||||||
