SUMMARY:Algebraic and enumerative combinatorics seminar-Katie Waddle
CLASS:PUBLIC
DESCRIPTION:TITLE: Spherical friezes\n\nSpeaker\n Katie Waddle\n\nAffiliat
 ion\n University of Michigan\n\nLocation\n MC 5479\n\n ABSTRACT: A fundam
 ental problem in spherical distance geometry aims\nto recover an $n$-tuple
  of points on a 2-sphere in $\\mathbb{R}^3$\,\nviewed up to oriented isome
 try\, from $O(n)$ input measurements. This\ntalk will discuss an algebraic
  solution to this problem using only the\nfour arithmetic operations. We w
 ill 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 t
 he Laurent phenomenon.\n\nTHERE WILL BE A PRE-SEMINAR PRESENTING RELEVANT 
 BACKGROUND AT THE\nBEGINNING GRADUATE LEVEL STARTING AT 1PM\,
