We will introduce topological quivers and a procedure for developing a skew product akin to skew products for directed graphs. We provide a characterization of the topological quivers which arise as the skew product, and investigate the ramifications of a cocycle on the associated Cuntz-Pimsner algebra. The cocycle determines a coaction, and we investigate the relationship between the coaction crossed product and the skew product quiver.
Our C*-Seminar will still (as it was last year) be on Wednesdays, but the time will now be a bit different: 1:30-2:45 pm (Arizona time, no daylight savings), meeting both in person (WXLR A311) and via zoom.
Also new: it's now the ASUERAU C*-Seminar (so, joint with our friends Lara and Mitch at Embry-Riddle Aeronautical University up the road in Prescott).
(Please email the organizer John Quigg quigg@asu.edu to be put on the email list if you would like to receive the link to the zoom seminar.)
