Let $K(z,\zeta)$ be the solution of

32.5.1 $K(z,\zeta)=k\mathop{\mathrm{Ai}\/}\nolimits\!\left(\frac{z+\zeta}{2}\right)+% \frac{k^{2}}{4}\*\int_{z}^{\infty}\!\!\!\int_{z}^{\infty}K(z,s)\mathop{\mathrm% {Ai}\/}\nolimits\!\left(\frac{s+t}{2}\right)\mathop{\mathrm{Ai}\/}\nolimits\!% \left(\frac{t+\zeta}{2}\right)dsdt,$

Symbols:: $\mathop{\mathrm{Ai}\/}\nolimits\!\left(z\right)$ : Airy function, : differential of , $\int$ : integral, : real, : real and $K(z,\zeta)$ : solution
