title = "On the Navarro-Willems conjecture for blocks of finite groups",
abstract = "We prove that a set of characters of a finite group can only be the set of characters for principal blocks of the group at two different primes when the primes do not divide the group order. This confirms a conjecture of Navarro and Willems in the case of principal blocks.",
