A uniqueness and existence theorem for a singular third-order boundary value problem on $[0,\infty)$.
(English)
[J] Appl. Math. Lett. 15, No.4, 445-451 (2002). ISSN 0893-9659

Summary: It is proved that the singular third-order boundary value problem $$y'''=f(y),\quad y(0) = 0,\quad y(+\infty) = 1,\quad y'(+\infty) = y''(+\infty) = 0,$$ has a unique solution. Here, $f(y) = (1-y)^{\lambda}g(y)$, $\lambda > 0$, $g(y)$ is positive and continuous on $(0,1]$. The problem arises in the study of draining and coating flows.
