Inequalities for Finite Group Permutation Modules
If f is a nonzero complex-valued function defined on a finite abelian group A and f̂ is its Fourier transform, then | supp(f)|| supp(f̂)| ≥ |A|, where supp(f) and supp(f̂) are the supports of f and f̂ . In this paper we generalize this known result in several directions. In particular, we prove an analogous inequality where the abelian group A is replaced by a transitive right G-set, where G is an ...
متن کاملRational permutation modules for finite groups
By the Artin Induction theorem,C(G) is a finite abelian group with exponent dividing the order of G. Some work on this sequence has already been done. In [14] and [16], Ritter and Segal proved that C(G) = 0 for G a finite p–group. Serre [17, p. 104] remarked that C(G) / = 0 for G = Z/3 × Q8 (the direct product of a cyclic group of order 3 and a quaternion group of order 8). Berz [2] gave a nice...
متن کاملPermutation Presentations of Modules over Finite Groups
We introduce a notion of permutation presentations of modules over finite groups, and completely determine finite groups over which every module has a permutation presentation. To get this result, we prove that every coflasque module over a cyclic p-group is permutation projective.
متن کاملThe group of endo-permutation modules
The group D(P ) of all endo-permutation modules for a finite p-group P is a finitely generated abelian group. We prove that its torsion-free rank is equal to the number of conjugacy classes of non-cyclic subgroups of P . We also obtain partial results on its torsion subgroup. We determine next the structure of Q⊗D(−) viewed as a functor, which turns out to be a simple functor SE,Q , indexed by ...
متن کاملGeneric Idempotent Modules for a Finite Group
Let G be a nite group and k an algebraically closed eld of characteristic p. Let F U be the Rickard idempotent kG-module corresponding to the set U of subvarieties of the cohomology variety VG which are not irreducible components. We show that F U is a nite sum of generic modules corresponding to the irreducible components of VG. In this context, a generic module is an indecomposable module of ...
