Brauer characters and rationality
Mathematische Zeitschrift, 2013Let \(G\) be a finite group and let \(p\) be a prime. In this paper, it is proved that \(G\) has a non-trivial rational valued irreducible \(p\)-Brauer character if and only if \(G\) has a non-trivial rational element of order prime to \(p\). The proof relies on the classification of the finite simple groups.

It is known that a finite group has even order if and only if it has an irreducible character that is rational valued. In this paper, it is shown that the same is true when ordinary characters are replaced by \(p\)-Brauer characters for \(p\) an odd prime (the result fails for \(p=2\)). A stronger result is proved for \(G\) solvable.

Characters, Brauer characters, and local Brauer groups
Communications in Algebra, 2020Let p be a prime. Let G be a finite group, and let χ be an irreducible character of G. Suppose F is a finite extension of Qp, the field of p-adic numbers.

Determination of Brauer Characters
Canadian Journal of Mathematics, 1974The purpose of this note is to show that the values of an irreducible (Brauer) character are the characteristic values of a matrix with non-negative rational integers. The construction of these integral matrices is done by a description of a representation of the Grothendieck ring of the category of modules over the group algebra.
