论文摘要
欧拉发现了五角数定理的结果，发现了除数总和的复发。以类似的想法，也是由Ewell在1977年的作品所激发的，我们证明了某些除数函数和三角形数字的新复发。
Euler discovered recurrence for divisor sum functions as a consequence of the pentagonal numbers theorem. With similar idea and also motivated by Ewell's work in 1977, we prove new recurrences for certain divisor sum functions and triangular numbers.
