SUMMARY:Algebraic Combinatorics Seminar - Lukas Nabergall
CLASS:PUBLIC
DESCRIPTION:TITLE: Enumerating hereditary classes of chord diagrams\n\nSpe
 aker:\n Lukas Nabergall\n\nAffiliation:\n University of Waterloo\n\nZoom:\
 n Contact Stephen Melczer\n\nABSTRACT:\n\nA class of combinatorial structu
 res is hereditary if membership in the\nclass is closed under taking subst
 ructures. Hereditary classes have\nbeen extensively studied for a variety 
 of objects\, notably graphs and\npermutations. A central problem is to det
 ermine the number of objects\nof size n in a given hereditary class. We di
 scuss this problem for\nchord diagrams\, perfect matchings of [2n].
