SUMMARY:Algebraic Combinatorics Seminar - Oliver Pechenik
CLASS:PUBLIC
DESCRIPTION:TITLE: Dynamics of plane partitions\n\nSpeaker:\n Oliver Peche
 nik\n\nAffiliation:\n University of Waterloo\n\nZoom:\n Contact Karen Yeat
 s\n\nABSTRACT:\n\nConsider a plane partition P in an a X b X c box. The ro
 wmotion\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 divisor with\na+
 b+c-1. This confirms a 1995 conjecture of Peter Cameron and Dmitri\nFon-De
 r-Flaass. (Based on joint works with Kevin Dilks & Jessica\nStriker and wi
 th Becky Patrias.)
