Abstract
Let $r\geq 1$ be an integer, $\mathbf{a}=(a_1,\dots,a_r)$ a vector of positive
integers, and let $D\geq 1$ be a common multiple of $a_1,\dots,a_r$. We prove
that if $D=1$ or $D$ is a prime number then the restricted partition function
$p_{\mathbf{a}}(n) := $ the number of integer solutions $(x_1,\dots,x_r)$ to $\sum_{j=1}^r
a_j x_j=n$, with $x_1\geq 0, \dots, x_r\geq 0$, can be computed by solving a
system of linear equations with coefficients that are values of Bernoulli
polynomials and Bernoulli–Barnes numbers.
