We organize the 6th edition of the CECAM workshop on Green’s functions, which will gather together the latest advances in the field. In particular we will discuss the new strategies to improve GW calculations, novel approaches to go beyond the GW method, new methods to treat electron-electron and electron-phonon correlations on an equal footing, advances in neighboring fields such as DFT, DMFT, and 2RDM, new insights such as, for example, the importance of the inclusion of the continuum states.
