The Riemann Series Theorem, also known as the Riemann rearrangement theorem, is a result in the field of analysis concerning the summation of series of real or complex numbers. The theorem states that if a series is conditionally convergent, the terms of that series can be rearranged in such a way that the rearranged series converges to any real number, or even diverges.
