"In this thesis, the theory of the g-factor of bound electrons and muons is presented. For\r\nlight muonic ions, we include one-loop self-energy as well as one- and two-loop vacuum\r\npolarization corrections with the interaction with the strong nuclear potential taken into\r\naccount to all orders. Furthermore, we include effects due to nuclear structure and mass.\r\nWe show that our theory for the bound-muon g-factor, combined with possible future\r\nbound-muon experiments, can be used to improve the accuracy of the muon mass by one\r\norder of magnitude. Alternatively, our approach constitutes an independent access to\r\nthe controversial anomalous magnetic moment of the free muon. Furthermore, two-loop\r\nself-energy corrections to the bound-electron g-factor are investigated theoretically to\r\nall orders in the nuclear coupling strength parameter Z α (alpha). Formulas are derived in the\r\nframework of the two-time Green's function method, and the separation of divergences\r\nis performed by dimensional regularization. Our numerical evaluation by treating the\r\nnuclear Coulomb interaction in the intermediate-state propagators to zero and first order\r\nshow that such two-loop terms are mandatory to take into account in stringent tests of\r\nquantum electrodynamics with the bound-electron g-factor, and in projected near-future\r\ndeterminations of fundamental constants."^^ .
