Computing group cohomology rings cimmel tart eloadast.


absztrakt:


   One way to compute the mod p cohomology ring of a finite group
is to construct a sufficiently long initial segment of the minimal
projective resolution and read off a presentation of the cohomology
ring out to that degree. Using a noncommutative Grobner basis method for
constructing the minimal resolution, Simon King and the author
successfully computed the cohomology rings of all 2328 groups of order
128.
They have also verified the strong version of Dave Benson's regularity
conjecture for all groups of order less than 256.
