1.
Moreover, we find that the sum of the coefficients of theseries has a close relation with the number of Schroder system with n element and theexact lower bound of convergence radius of Euler s series can be derived from the value ofconvergence radius of the corresponding exponential generating function.
而且,我们发现Euler级数的系数和具有n个元素的Schroder系的个数之间的联系,以及Euler级数收敛半径的确切下界可通过相应的指母函数的收敛半径得到。
2.
Solving R-reusable permutation of inexactly distinct elements with exponential generating functions is quite effectual.
指母函数是求解不尽相异元素r可重排列问题的有效方法,当求出对应问题的指母函数后,指母函数中各xr项的系数的规范化就成了问题求解的关键。
