SUMMARY:Algebraic Graph Theory - Josse van Dobben de Bruyn
CLASS:PUBLIC
DESCRIPTION:TITLE: Gonality of graphs – a survey\n\nSPEAKER:\n Josse van 
 Dobben de Bruyn\n\nAFFILIATION: \n Technical University of Denmark (DTU)\n
 \nLOCATION:\n Please contact Sabrina Lato for Zoom link.\n\nABSTRACT: Over
  the past 30 or so years\, the realization that graphs\ncan be viewed as d
 iscrete analogues of Riemann surfaces has led to a\nfruitful interplay bet
 ween algebraic geometry\, tropical geometry\, and\ngraph theory. Among oth
 er things\, this has led to the study of new\ngraph parameters\, including
  various notions of the _gonality_ of a\ngraph. In addition to its ties w
 ith algebraic and tropical geometry\,\ngraph gonality also turns out to ha
 ve connections with chip-firing\ngames\, structural graph theory\, and par
 ametrized complexity. In this\ntalk\, I will introduce the two most common
  types of graph gonality\n(namely\, _divisorial gonality_ and _stable gon
 ality_) and survey the\nmost important results and open problems in this f
 ield\, including the\nconnections with the aforementioned topics.
