Abstract
Summary: ``For a sum of the form $\sum_k F(n,k)G(n,k)$, we set up two systems of equations involving shifts of $F(n, k)$ and $G(n, k)$. Then we solve the systems by utilizing the recursion of $F(n, k)$ and the method of undetermined coefficients. From the solutions, we derive linear recurrence relations for the sum. With this method, we prove many identities involving Bernoulli numbers and Stirling numbers.''
