Universal Algebra and Lattice Theory - Lecture 7: Complete lattices
Channel: Charlotte Aten
Date: 23/12/2020

This is from my old YouTube channel. My new channel can be found at https://www.youtube.com/@CharlotteAten

This is the seventh in a series of talks about universal algebra and lattice theory. I introduce the notion of a complete lattice and (at long last) show that the congruences and subuniverses of an algebra form lattices. I also go over early results of Dedekind on congruence lattices of groups and Funayama and Nakayama on congruence lattices of lattices.
