Query: On the restricted partition function II   Let $\mathbf a=(a_1,\ldots,a_r)$ be a vector of positive integers. In
continuation of a previous paper we present other formulas for the restricted
partition function $p_{\mathbf a}(n): = $ the number of integer solutions
$(x_1,\dots,x_r)$ to $\sum_{j=1}^r a_jx_j=n$ with $x_1\geq 0, \ldots, x_r\geq
0$.
