Research output: Contribution to journalArticlepeer-review


We obtain new Poisson type summation formulas with nodes ±n and with weights involving the function rk(n) that gives the number of representations of a positive integer n as the sum of k squares. Our results extend summation formulas due to Guinand and Meyer that involve the sum-of-three-squares function r3(n).
