| the property of an infinite series that converges while the series formed by replacing each term in the given series with its absolute value diverges; the property of an infinite series that converges when the order of the terms is altered. Compare absolute convergence (def. 1). |
| conditional convergence n. Convergence of an infinite series that lacks absolute convergence, such as 1/2 + 1/3 + 1/4 .... |
