abstract = {Our aim is to present new expressions for the Drazin inverse of anti-triangular block matrices under some circumstances. Applying the established new formulae for anti-triangular block matrices, we derive explicit representations for the Drazin inverse of a  2×2 complex block matrix under corresponding assumptions. We extend several well known results in the literature in this way.}
