Abstract:
Based on a large amount of examples, which we have checked so far, we conjecture that where is a prime and the sum runs through the set of irreducible Brauer characters in characteristic of the finite group . We prove the conjecture simultaneously for -solvable groups and groups of Lie type in the defining characteristic. In non-defining characteristics we give asymptotically an affirmative answer in many cases.
