Student Combinatorics Seminar Date:  Monday, April 08, 2013 Location:  3088 East Hall (4:00 PM to 5:00 PM) Title:  A character-building way of computing chromatic polynomials Abstract:   We will attempt to compute the chromatic polynomial of an N-by-N square grid, or at least what it looks like when N is large. By judicious use of handwaving on the one hand, and representations of the (Temperley-Lieb) algebra of squiggles on the other, we will relate this to the "six-vertex model" (think alternating sign matrices), which can be solved "exactly". Time will hopefully prevent us from having to write down the final answer. Speaker:  Elena Yudovina Institution:  UM Event Organizer:        Edit this event (login required).
