We augment the time-linear formulation of the Kadanoff-Baym equations for systems of interacting electrons and quantized phonons or photons with the $G\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{W}$ approximation, the Coulomb interaction $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{W}$ being dynamically screened by both electron-hole pairs and bosonic particles. We also show how to combine different approximations to …
