方程ax+by+cz=n的非负整数解的个数及其与二次剩余的关系

Number of Non-negative Integer Solutions of the Equation ax+by+cz=n and its Relation with Quadratic Residues

Damanvir Singh Binner

摘要:

2000年,A. Tripathi使用母函数获得了方程ax + by = n的非负解(x,y)的数量公式,其中a、b和n均为正整数。我们把这个过程推广到方程ax + by + cz = n的解的个数。这个公式使我们在方程ax + by + cz = n的解的个数和二次剩余之间找到了令人惊讶的联系。作为我们工作的结果,我们能够证明高斯和西尔维斯特在十九世纪的两个基本结果之间的等价性,这两个结果通常被认为是独立的。

英文摘要:

In 2000, A. Tripathi used generating functions to obtain a formula for the number of non-negative solutions (x,y) of the equation ax + by = n where a, b and n are given positive integers. We generalize this procedure for the number of solutions of the equation ax + by + cz = n. The formula leads us to a surprising connection between the number of solutions of the equation ax + by + cz = n and quadratic residues. As a consequence of our work, we are able to prove the equivalence between two fundamental results by Gauss and Sylvester in the nineteenth century which are generally viewed to be independent.
