34) There is a close connection between the kernel $I(x,y)$ comming up in the formal expression for the $S$-matrix in perturbation theory $S{=}_{\text{in}}{\langle 0\left|S\right|0\rangle }_{\text{in}}:exp\int dxdy{\varphi }_{\text{in}}^{+}\left(x\right)I(x,y){\varphi }_{\text{in}}\left(y\right):$ and the fundamental solution $S_R(x,y;A)$ resp. $S_A(x,y;A)$ of the wave equation (11). $G=G^0+G^{0}I{G}^0$ where $G^0$ denotes the fundamental solution of the free equation with Feynman boundary conditions. Then $G$ is a solution of the equation $G=G^0-i{G}^0\neg AG$ On the other hand $S_R$ resp. $S_A$ are solutions of the Yang-Feldman equation (12) $S_{\genfrac{}{}{0pt}{}{R}{A}}(x,y;A)=S_{\genfrac{}{}{0pt}{}{R}{A}}^0(x-y)-i\int dz{S}_{\genfrac{}{}{0pt}{}{R}{A}}^0(x-z)\neg A\left(z\right)S_{\genfrac{}{}{0pt}{}{R}{A}}(z,y;A)$.
