| Issue | Solution | |-------|----------| | – blurry equations | Find the Dover 2003 edition (ISBN 0486428273). Avoid 1971 McGraw-Hill scans. | | Missing factor of (i) in Green’s function definitions | Check Sec. 3.1: F&W define (iG(x,x') = \langle T\psi(x)\psi^\dagger(x')\rangle). Many PDFs misprint this. | | Matsubara sums: (\sum_n) vs (\oint) | Their derivation (Ch.4) uses contour integration explicitly – a major strength. Look for the key equation (4.53) in your PDF; if missing, the scan is incomplete. | | No color in diagrams – all grayscale | Fine – but ensure the dashed/solid lines are distinguishable. If not, annotate with colored PDF software. |
