【 摘 要 】

We study the problem when the product of two non-linear Galois conjugate characters of a finite group is irreducible. We also prove new results on irreducible tensor products of cross-characteristic Brauer characters of quasisimple groups of Lie type. (C) 2021 Elsevier Inc. All rights reserved.
