3-核划分三元组的算术恒等式和同余式

Arithmetic Identities and Congruences for Partition Triples with 3-cores

Liuquan Wang

摘要:

令${{B}_{3}}(n)$表示$n$的分区三元组的数量,其中每个分区是3核的。借助于生成函数的操作,我们找到了${{B}_{3}}(n)$的算术恒等式和同余式的几个无穷族。另外,设$ω(n)$表示非负整数$n$的表示数,形式为$x_{1}^{2}+x_{2}^{2}+x_{3}^{2}+3y_{1}^{2}+3y_{2}^{2}+3y_{3}^{2}$ with ${{x}_{1}},{{x}_{2}},{{x}_{3}},{{y}_{1}},{{y}_{2}},{{y}_{3}}\in \mathbb{Z}.$,我们发现了${{B}_{3}}(n)$与$ω(n)$之间的三种算术关系,如$ω(6n+5)=4{{B}_{3}}(6n+4).$

英文摘要:

Let ${{B}_{3}}(n)$ denote the number of partition triples of $n$ where each partition is 3-core. With the help of generating function manipulations, we find several infinite families of arithmetic identities and congruences for ${{B}_{3}}(n)$. Moreover, let $ω(n)$ denote the number of representations of a nonnegative integer $n$ in the form $x_{1}^{2}+x_{2}^{2}+x_{3}^{2}+3y_{1}^{2}+3y_{2}^{2}+3y_{3}^{2}$ with ${{x}_{1}},{{x}_{2}},{{x}_{3}},{{y}_{1}},{{y}_{2}},{{y}_{3}}\in \mathbb{Z}.$ We find three arithmetic relations between ${{B}_{3}}(n)$ and $ω(n)$, such as $ω(6n+5)=4{{B}_{3}}(6n+4).$
