Coactions and Skew Products for Topological Quivers
Lucas Hall
Given a cocycle on a topological quiver by a locally compact group, the author constructs a skew product topological quiver, and determines conditions under which a topological qui…
The Modular Stone-von Neumann Theorem
Lucas Hall, Leonard Huang, John Quigg
In this paper, we use the tools of nonabelian duality to formulate and prove a far-reaching generalization of the Stone-von Neumann Theorem to modular representations of actions an…
Groupoid Semidirect Product Fell Bundles II- Principal Actions and Stabilization
Lucas Hall, S. Kaliszewski, John Quigg +1
Given a free and proper action of a groupoid on a Fell bundle (over another groupoid), we give an equivalence between the semidirect-product and the generalized-fixed-point Fell bu…
Groupoid Semidirect Product Fell Bundles I- Actions by Isomorphisms
Lucas Hall, S. Kaliszewski, John Quigg +1
Given an action of a groupoid by isomorphisms on a Fell bundle (over another groupoid), we form a semidirect-product Fell bundle, and prove that its -algebra is isomorphic t…
