Title: A Multijection of Cokernels

Speaker: Alex McDonough
Affiliation: UC Davis

Absract:

I discovered an intriguing linear algebra relationship which I call a multijection. I used this construction to solve an open problem about higher-dimensional sandpile groups, but I think that it has more to say. In this talk, I will focus on sharing the most general version of the multijection that I know of, which involves a family of beautiful periodic tilings. This talk uses mostly linear algebra, so it should be accessible to a general math audience.
