§32.5 Integral Equations

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

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

where k is a real constant, and \operatorname{Ai}\left(z\right) is defined in §9.2. Then

32.5.2 w(z)=K(z,z),

satisfies \mbox{P}_{\mbox{\scriptsize II}} with \alpha=0 and the boundary condition

32.5.3 w(z)\sim k\operatorname{Ai}\left(z\right),z\to+\infty.
