Fr. Jiang, On the asymptotic solutions of boundary value problems for a class of systems of nonlinear differential equations (I), APP MATH ME, 22(3), 2001, pp. 282-293
A new method is applied to study the asymptotic behavior of solutions of bo
undary value problems for a class of systems of nonlinear differential equa
tions
u" = nu, epsilon nu" + f(x, u, u')nu' - g(x, u, u') nu = 0 (0 < epsilon muc
h less than 1).
The asymptotic expansions of solutions are constructed, the remainders are
estimated. The former works are improved and generalized.
