SUMMARY:Algebraic and enumerative combinatorics seminar-Katie Waddle
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Spherical friezes\n\nSpeaker\n Katie Waddle
 \n\nAffiliation\n University of Michigan\n\nLocation\n MC 5479\n\n ABSTRA
 CT: A fundamental problem in spherical distance geometry aims\nto recover 
 an $n$-tuple of points on a 2-sphere in $\\mathbb{R}^3$\,\nviewed up to or
 iented isometry\, from $O(n)$ input measurements. This\ntalk will discuss 
 an algebraic solution to this problem using only the\nfour arithmetic oper
 ations. We will show how a new type of frieze\npattern can be employed to 
 arrange the measurement data. These friezes\nexhibit glide symmetry and a 
 version of the Laurent phenomenon.\n\nTHERE WILL BE A PRE-SEMINAR PRESENTI
 NG RELEVANT BACKGROUND AT THE\nBEGINNING GRADUATE LEVEL STARTING AT 1PM\,\
