SUMMARY:Algebraic Combinatorics - Jean-Philippe Labbé
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTitle: Lineup polytopes and applications in quantum
  physics\n\nSpeaker:\n Jean-Philippe Labbé\n\nAffiliation:\n Université 
 du Québec\n\nLocation:\n MC 5479 contact Olya Mandelshtam for Zoom link\n
 \nAbstract:  To put it simply\, Pauli's exclusion principle is the\nreaso
 n why we can't walk through walls without getting hurt. Pauli won\nthe Nob
 el Prize in Physics in 1945 for the formulation of this\nprinciple. A few 
 years later\, this principle received a geometrical\nformulation that is s
 till overlooked today. This formulation uses the\neigenvalues of certain m
 atrices (which represent a system of\nelementary particles\, for example e
 lectrons). These eigenvalues form a\nsymmetric geometric object obtained b
 y cutting a hypercube: it is a\nhypersimplex.\n
