SummerTime package| Description: |
SummerTime is a Mathematica package performing the high-precision calculation of the multiple
sums with factorized summand. More specifically, it calculates sums of the following form
\[\sum_{(n_1,\ldots,n_K)\in S} f_1(n_1)\ldots f_K(n_K)\] where each factor $f_i(n)$ is a hypergeometric term (i.e.
$f_i(n+1)/f_i(n)$ is a rational function) and $S$ is a region in $\mathbb{Z}^n$ determined by a set of inequalities
of the form $n_i \leqslant n_j$ for each parent-child pair $i$-$j$ from some directed rooted tree graph with
vertices labeled by $0,1,\ldots K$. The root $n_0$ is some integer. |
