3. R. BALIAN, G. PARISI, A. VOROS, in: “Feynman Path Integrals”, Springer Lecture Notes in Physics, vol. 106 (1979). That article contains the following misprints:-Eqs. (4.7) and (4.10): a factor i is missing in front of $$\sum\limits_{m \ne 0} {(...)}$$ -in the two lines above Eq.(4.13): replace $$\mathop \Sigma \limits_{k = 0}^\infty$$ by $$\mathop \Sigma \limits_{k = - 2}^\infty$$ -in Eq.(4.13): replace $$\mathop \Sigma \limits_{\ell = 0}^\infty$$ by $$\mathop \Sigma \limits_{\ell = - 1}^\infty$$ -in the second line after Eq.(4.13): replace ρ2 j−1 (o) by ρ2 j−2 (o) -in the seventh line after Eq.(4.13): replace ρ2 j (o) by ρ2 j−1 (o)
