Hi everyone,

The next Mums talk will occur next Friday 14. It will be an introduction to the principles of universal algebra using categorical notions. In particular, we want to impress on the listener the importance of the notion of universal constructions in algebra. The beauty of universal algebra and category theory lies in their broad descriptive power, rather than in their depth.

Time: 5pm – 7pm, Friday February 14, 2014

Location: TBD (somewhere in BA, check Facebook for the update)

Speaker: Paul Sacawa

Title: Universal Algebra using the Language of Category Theory

Abstract: An introduction to universal algebra using the language of category theory. Cats, functors, universal constructions; omega-algebras, free objects, varieties, and the isomorphism theorems. We end by describing some universal constructions with easy descriptions in varietal categories.

Intended audience: It’s enough to know some basic algebra (which we use just as examples): group, normal subgroup, quotient group, ring, ideal, quotient ring. It would be nice to come in with the idea of categories in your head.
