Popis: | Let G be a finite group, \(\Lambda\) an absolutely irreducible \({\mathbb{Z}}[G]\) -module and w a weight of \(\Lambda\) . To any Galois covering with group G we associate two correspondences, the Schur and the Kanev correspondence. We work out their relation and compute their invariants. Using this, we give some new examples of Prym–Tyurin varieties. |
