Equivariant K-theory, generalized symmetric products, and twisted Heisenberg algebra
For a space X acted by a finite group Γ, the product space X affords a natural action of the wreath product Γn = Γ n ⋊ Sn. The direct sum of equivariant K-groups ⊕ n≥0 KΓn(X )⊗C were shown earlier by the author to carry several interesting algebraic structures. In this paper we study the Kgroups K H̃Γn (X) of Γn-equivariant Clifford supermodules on X . We show that F Γ (X) = ⊕ n≥0 H̃Γn (X)⊗ C is ...
متن کاملTwisted Equivariant K-theory for Proper actions of Discrete Groups
We will make a construction of twisted equivairant K-theory for proper actions of discrete groups by using ideas of Lück and Oliver [16] to expand a construction of Adem and Ruan [1].
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولDistortion of Wreath Products in Some Finitely Presented Groups
Wreath products such as Z ≀ Z are not finitely-presentable yet can occur as subgroups of finitely presented groups. Here we compute the distortion of Z ≀ Z as a subgroup of Thompson’s group F and as a subgroup of Baumslag’s metabelian group G. We find that Z ≀ Z is undistorted in F but is at least exponentially distorted in G.
متن کاملGroup Codes based on Wreath Products of Complex Reflection Groups
Group codes based on wreath products of complex matrix groups are constructed. Efficient algorithms for encoding and decoding these codes are described.
