    On contractibility of th orbit space of a G-poset of Brauer pairs
    (Elsevier, 1999-02-15) Barker, L.
    Given ap-blockbof a finite groupG, we show that theG-poset of Brauer pairs strictly containing (1,b) has contractibleG-orbit space. A similar result is proved for certainG-posets ofp-subgroups. Both results generalise P. Symonds' verification of a conjecture of P. Webb. © 1999 Academic Press.
