Title:	Many-electron QED corrections to the hyperfine splitting in heavy Li-like ions
Abstract:	A rigorous evaluation of the screened radiative and two-photon exchange corrections to the hyperfine structure in lithiumlike heavy ions is presented. This completes the calculations of the many-electron QED corrections to the hyperfine splitting in the second-order perturbation theory. As a result, the theoretical accuracy of the specific difference between the hyperfine splitting values of H- and Li-like Bi ions is improved by an order of magnitude. This opens a possibility for the stringent test of the many-electron QED effects on a percent level in the strongest electromagnetic field available at present for experimental study.
