Abstract: In this contribution, we highlight a problem in estimation of the mass of axion dark matter in the scenario where the Peccei-Quinn symmetry is broken after inflation. In order to obtain a definite prediction for its mass, it is necessary to evaluate its relic abundance precisely by taking account of the production from cosmic strings and domain walls. After reviewing a long-standing controversy about the axion production efficiency from decaying strings, several recent approaches aiming at resolving the uncertainty are discussed.
