SUMMARY:Algebraic Combinatorics Seminar - Oliver Pechenik
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Dynamics of plane partitions\n\nSpeaker:\n 
 Oliver Pechenik\n\nAffiliation:\n University of À¶Ý®ÊÓƵ\n\nZoom:\n Contac
 t Karen Yeats\n\nABSTRACT:\n\nConsider a plane partition P in an a X b X c
  box. The rowmotion\noperator sends P to the plane partition generated by 
 the minimal\nelements of its complement. We show rowmotion resonates with 
 frequency\na+b+c-1\, in the sense that each orbit size shares a prime divi
 sor with\na+b+c-1. This confirms a 1995 conjecture of Peter Cameron and Dm
 itri\nFon-Der-Flaass. (Based on joint works with Kevin Dilks & Jessica\nSt
 riker and with Becky Patrias.)\n
