By Renaming If Necessary

Date: 11/10/2017

Time: 3:00PM-4:00PM

Place: 422 Armstrong Hall

**Abstract:**We explain here how renaming can be insufficient. In particular, we

show that in many rings, there exists a function that is not a conjugate

of some polynomial function. The only tools needed are from typical

undergraduate Mathematics courses, such as Linear Algebra. If time

permits, we will show some relevant computations in MathCAD, and in

the Universal Algebra Calculator. This talk is intended to be accessible

to undergraduate students.

All are welcome.
