SUMMARY:Algebraic and enumerative combinatorics seminar - Nathan\nPagliarol
 i- Counting triangulations from bootstrapping tensor\nintegrals
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Nathan Pagliaroli\n\nAFFILIATION:\n University of Wa
 terloo\n\nLOCATION:\n MC 5417\n\nABSTRACT: Tensor integrals are the gener
 ating functions of\ntriangulations of pseudo-manifolds. Such triangulation
 s are\nconstructed by gluing simplices along facets. These generating\nfun
 ctions satisfy an infinite system of recursive equations called the\nDyson
 -Schwinger equations\, derived by reclusively gluing together\ntriangulati
 ons. Such integrals also satisfy positivity constraints. By\ncombining the
  Dyson-Schwinger equations and positivity constraints in\na process called
  bootstrapping we are able to deduce known results for\nthe generating fun
 ctions of certain classes of triangulations as well\nas find new explicit 
 formulae. This talk is based on joint work with\nCarlos I. Perez-Sanchez a
 nd Brayden Smith.\n\nTHERE WILL BE A PRE-SEMINAR PRESENTING RELEVANT BACK
 GROUND AT THE\nBEGINNING GRADUATE LEVEL STARTING AT 1:30PM.
