For a given flag variety, we characterize the primes p for which there exists a weight l such that the hard Lefschetz theorem holds for multiplication by l on the cohomology of the flag variety with coefficients in an infinite field of characteristic p.

Abstract
For a given flag variety, we characterize the primes p for which there exists a weight l such that the hard Lefschetz theorem holds for multiplication by l on the cohomology of the flag variety with coefficients in an infinite field of characteristic p.File in questo prodotto:
