"Whether (1) converges depends on the values of the complex numbers α and x. More precisely: 1. If x < 1, the series converges absolutely for any complex number α. 2. If x = 1, the series converges absolutely if and only if either Re(α) > 0 or α = 0, where Re(α) denotes the real part of α. 3. If x = 1 and x ≠ −1, the series converges if and only if Re(α) > −1.
