我們從單峰數列得到研究靈感,藉由討論兩種特殊的停車函數:V-停車函數和Lambda-停車函數,我們證明了驚人的事實:V-停車函數的數量就是卡特蘭數,以及Lambda-停車函數的數量就是Fine數。(在附錄A中,我們以組合證明的方式,驗證了卡特蘭三角的對角和是Fine數。)
We introduce two special types of parking function, V-parking function and Lambda-parking function, which are inspired by the unimodal sequence.
Then, we prove the suprising facts that the number of V-parking functions are Catalan numbers and the number of Lambda-parking functions are Fine numbers. (In appendix A, we verify that the diagonal sums of Catalan triangle are Fine numbers by giving bijections.)
