本文研究了simsun排列的左峰、内峰和上下运行之间的关系。研究了生成多项式的性质,包括递归关系、生成函数和实根性。此外,我们还引入并研究了第二类simsun排列。
In this paper, we study the relationship among left peaks, interior peaks and up-down runs of simsun permutations. Properties of the generating polynomials, including the recurrence relation, generating function and real-rootedness are studied. Moreover, we introduce and study simsun permutations of the second kind.
