摘要
利用递推关系和发生函数,研究塔形Dyck路以及所有路径与x轴围成的区域面积,得到所有半长为n的塔形Dyck路的计数公式,和所有半长为n的塔形Dyck路与x轴所围区域总面积的计数公式.
By using recursive relations and generating functions, the pyramidal Dyck paths and the total area of the region surrounded by the x-axis and all paths were studied and the counting formula of the number of all pyramid Dyck paths with semi-length of n and the counting formula of the total area of the region surrounded bv x-axis and all pyramid Dyck- paths with semi-length of n were obtained.
