Abstract. Let q be any complex number other than 0 and 1. We first asymptotically express the logarithmic q-difference log f(qz) − log f(z) in terms of the logarithmic derivative f /f for any meromorphic function f of order strictly less than 1/2. Then we show the assumption that the order strictly less than 1/2 is sharp. Finally, we prove a q-difference analogue of the Wiman–Valiron theorem for entire functions of order strictly less than 1/2.
