A Galois-theoretic approach to Kanev's correspondence (Q2481317)

From author's abstract: 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.
