개요

  • 분할의 rank = 분할에서 가장 큰 수 - 분할의 크기
    • 9의 분할인 {7,1,1}의 경우, rank=7-3=4
    • 9의 분할인 {4,3,1,1}의 경우, rank=4-4=0
  • 분할의 crank
    • 분할에서 가장 큰 수 (1이 포함되지 않는 분할의 경우)
    • 분할에서 "1의개수"보다 큰 수 - 1의 개수 (1이 포함되는 경우)
    • 9의 분할인 {7,1,1}의 경우, crank=1-2=-1
    • 9의 분할인 {4,3,1,1}의 경우, crank=2-2=0
  • 200까지의 분할수 목록 항목 참조

재미있는 사실

  • In 1944, the crank was first hinted at by Freeman Dyson (2), then an undergraduate at Cambridge University. He had written an article, titled Some Guesses in the Theory of Partitions, for Eureka, the undergraduate mathematics journal of Cambridge.
