%0 Journal Article %T The Isaacs-Navarro Conjecture for covering groups of the symmetric and alternating groups in odd characteristic %A Jean-Baptiste Gramain %J Mathematics %D 2010 %I arXiv %X In this paper, we prove that a refinement of the Alperin-McKay Conjecture for $p$-blocks of finite groups, formulated by I. M. Isaacs and G. Navarro in 2002, holds for all covering groups of the symmetric and alternating groups, whenever $p$ is an odd prime. %U http://arxiv.org/abs/1003.4704v2
