2010 Mathematics Subject Classification: Primary: 40A05 [MSN][ZBL]

A criterion for the convergence of series of complex numbers, established by P. du Bois-Reymond.

If the series of complex numbers $\sum_n b_n$ converges and the series of complex numbers $\sum_n (a_n-a_{n+1})$ converges absolutely, then the series $\sum_n a_n b_n$ converges.
