Donovan's conjecture and extensions by the centralizer of a defect group
نویسندگان
چکیده
We consider Donovan's conjecture in the context of blocks groups G with defect group D and normal subgroups N◁G such that G=CD(D∩N)N, extending similar results for abelian groups. As an application we show holds form Q8×C2n or Q8×Q8 defined over a discrete valuation ring.

Skew Products in the Centralizer of Compact Abelian Group Extensions
If Tψ is an ergodic group extension of a weakly mixing transformation T having minimal self-joinings, then it is shown that isomorphism between Tψ and its inverse implies isomorphism between T and T−1. However, if T satisfies the weaker condition of being simple it is shown that that isomorphism between Tψ and its inverse does not imply the isomorphism between T and T−1. This answers a question...
متن کاملThe Abelian Defect Group Conjecture
Let G be a nite group and k an algebraically closed eld of characteristic p > 0. If B is a block of the group algebra kG with defect group D, the Brauer correspondent of B is a block b of kN G (D). When D is abelian, the blocks B and b, although they are rarely isomorphic or even Morita equivalent, seem to be very closely related. For example, Alperin's Weight Conjecture predicts that they shou...
متن کاملFinite group extensions and the Atiyah conjecture
The Atiyah conjecture for a discrete group G states that the L-Betti numbers of a finite CW-complex with fundamental group G are integers if G is torsion-free, and in general that they are rational numbers with denominators determined by the finite subgroups of G. Here we establish conditions under which the Atiyah conjecture for a torsion-free group G implies the Atiyah conjecture for every fi...
