This is the first in a series of talks I’ll give on universal algebra and lattice theory this semester. It is the only one I’ll advertise on the calendar and is intended to serve as either as an introduction to the seminar/reading course/lecture series I’m running this semester or as a standalone talk on what these two related subjects are about and how I came to be interested in them. The relevant webpage is located at http://aten.cool/2020ua.html. Email me for the Zoom ID if you would like to attend and didn’t already get it.
