A spectral weight conserving formalism for Fermionic thermal Green's functions is presented. The formalism requires a generalization of the Dyson equation and the Baym-Kadanoff-Luttinger-Ward functional for the free energy. The figure shows the spectral function A (details are given in the article, see Fig. 2). Picture: M. Granath et al., pp. 147–152 in this issue.
