โฆ Synopsis
The differential equation
F"' + AFF" -I-BF12 = 0,
where A and B are arbitrary constants subject to different types of boundary conditions, is considered. This class of equations frequently occurs in boundary-layer theory. The proposed Dirichlet series method, in conjunction with an unconstrained optimization procedure, is found useful in analyzing these problems. The series so generated is analyzed using Euler transformation and Pad6 approximants.

## By a new approach, we prove in this paper that there exists Xo E (-l/2,0) such that the following third-order nonlinear boundary value problem for f(n): which arises in boundary layer theory in fluid mechanics, has a solution at least for any fixed X E (Xo, 0).
