Colloquium
3:30 p.m., Friday
Math 100
Dr. Fernando Rodriguez Villegas*
Univ. Texas (Austin)
Reflexive Loops: What's 12 got to do with it?
In this talk I will discuss an elementary fact about certain
polygonal paths in the plane (the reflexive loops of the title).
The statement should be understandable to any highschool student
but its proof will lead us to quite interesting mathematics: toric
varieties, braids, and the universal cover of SL_2(\R).
*Dr. Villegas is a candidate for a position in our department.
All faculty are urged to attend this lecture.
Refreshments will be served in Math Annex Room 1115, 3:15 p.m.
