Radiative corrections to bound-state properties in QED

Abstract

This talk summarizes some results on bound-state properties obtained since the previous (1998) RADCOR meeting. Recent results on radiative corrections to positronium decay width and the $g$-factor of a bound electron are described. A new approach to evaluating recoil corrections in systems consisting of particles with different masses is discussed.
