Representation Equivalent Bieberbach Groups and Strongly Isospectral Flat Manifolds
(Canadian Mathematical Soc, 2014-06)
Let Γ1 and Γ2 be Bieberbach groups contained in the full isometry group G of Rn. We provethat if the compact flat manifolds Γ1\Rn and Γ2\Rn are strongly isospectral, then the Bieberbachgroups Γ1 and Γ2 are representation ...
REALIZING PROFINITE REDUCED SPECIAL GROUPS
(PACIFIC JOURNAL MATHEMATICS, 2011)
Special groups are an axiomatization of the algebraic theory of quadratic forms over fields. It is known that any finite reduced special group is the special group of some field. We show that any special group that is the ...
Low-dimensional representations of the three component loop braid group
(American Institute of Physics, 2015-11)
Motivated by physical and topological applications, we study representations of the group LB3 of motions of 3 unlinked oriented circles in R3. Our point of view is to regard the three strand braid group B3 as a subgroup ...
Free actions of abelian p-groups on the n-Torus
(2005-01-01)
In this work we make some contributions to the theory of actions of abelian p-groups on the n-Torus Tn. Set H ≅ ℤpk1 h1 × ℤpk2h2 × ⋯ × ℤpkrhr, r ≥ 1, k1 ≥ k2 ≥ ⋯ ≥ kr ≥ 1, p prime. Suppose that the group H acts freely on ...
