SUMMARY:Algebraic Combinatorics Seminar - Colin Defant
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Semidistrim Lattices\n\nSpeaker:\n Colin De
 fant\n\nAffiliation:\n Princeton University\n\nZoom:\n Please email Olya 
 Mandelshtam\n\nABSTRACT:\n\nThis talk will introduce semidistrim lattices\
 , which generalize\nsemidistributive lattices and trim lattices\; these tw
 o families\, in\nturn\, generalize distributive lattices. We will discuss 
 structural\,\ntopological\, and dynamical properties of semidistrim lattic
 es. In\nparticular\, we will see how one can define a certain bijective\no
 perator on a semidistrim lattice called rowmotion\; this definition\nunifi
 es the definition that Barnard gave for semidistributive lattices\nand the
  definition that Thomas and Williams gave for trim lattices.\n
