Method for Obtaining Coefficients of Powers of Multivariate Generating Functions
نویسندگان
چکیده
There are several general concepts that allow obtaining explicit formulas for the coefficients of generating functions in one variable by using their powers. One such concept is application compositae functions. In previous studies, we have introduced a generalization multivariate and defined basic operations on bivariate The use these helps to obtain two variables. this paper, expand case three addition, describe way applying rational To confirm effectiveness proposed method, present detailed examples its function related Aztec diamond permutations with cycles.

A Method for Obtaining Generating Functions for Central Coefficients of Triangles
We present techniques for obtaining a generating function for the central coefficients of a triangle T (n, k), which is given by the expression [xH(x)] = ∑ n>k T (n, k)x , H(0) 6= 0. We also prove certain theorems for solving direct and inverse problems.
متن کاملA new method for computing asymptotics of diagonal coefficients of multivariate generating functions
Let P n∈Nd Fnx n be a multivariate generating function that converges in a neighborhood of the origin of C. We present a new, multivariate method for computing the asymptotics of the diagonal coefficients Fa1n,...,adn and show its superiority over the standard, univariate diagonal method. Several examples are given in detail.

Given an integer m ≥ 1, let ‖·‖ be a norm in R and let S+ denote the set of points d = (d0, . . . , dm) in R with nonnegative coordinates and such that ‖d‖ = 1. Consider for each 1 ≤ j ≤ m a function fj(z) that is analytic in an open neighborhood of the point z = 0 in the complex plane and with possibly negative Taylor coefficients. Given n = (n0, . . . , nm) in Z with nonnegative coordinates, ...
