On the minimal irreducibility of the unipotent characters of the finite unitary groups
Marco Antonio Pellegrini · 2009
Let G = PSU(n,q) and let χ be a non-trivial unipotent character of G. In this paper, we study when the restriction of χ to H is reducible for any proper subgroup H of G, proving that this is always the case, apart from a few isolated exceptions. © 2009 World Scientific Publishing Co. Pte. Ltd.
