For positive integers $n$ and $k$ , let $r_{k}(n)$ denote the number of representations of $n$ as a sum of $k$ squares, where representations with different orders and different signs are counted as distinct. For a given positive integer $m$ , by means of some properties of binomial coefficients, we derive some infinite families of congruences for $r_{k}(n)$ modulo $2^{m}$ . Furthermore, in view of these arithmetic properties of $r_{k}(n)$ , we establish many infinite families of congruences for the overpartition function and the overpartition pair function.

对于正整数$n$ 和$k$ , 让$r_{k}(n)$ 表示表示的数量$n$ 作为总和$k$ 正方形,其中具有不同顺序和不同符号的表示被视为不同的。对于给定的正整数$m$ ,通过二项式系数的一些性质,我们推导出一些无限的同余族$r_{k}(n)$ 模数$2^{m}$ . 此外,鉴于这些算术性质$r_{k}(n)$ ,我们为过度分区函数和过度分区对函数建立了许多无限的同余族。
