Abstract

Let G be a finite group, Λ an absolutely irreducible ℤ[G]-module and w a weight of Λ. 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. © 2007 Springer-Verlag.
