Cyclotomic Matrices and Graphs: Warwick

I’m continuing to tour my Cyclotomic Matrices and Graphs talk; today I presented it at the University of Warwick. Here’s the latest and greatest iteration of the slides, mostly unchanged except for the current state of the computer search for minimal noncyclotomics of at most ten vertices. I’d hoped to finish that this month, but the final round of growing in the most general case over the gaussian integers has progressed much slower than I expected. Given that some batches finished in a twentieth of the wall time others have consumed so far, I’m suspecting the reasons may be non-mathematical. However, I have finished the eisenstein integer case, and there are four new classes with Mahler measure less than 1.3, with representatives given in the slides.
