Multiple Solutions of Singular Perturbation Problems
Under certain conditions on g(x, u) we establish the existence and asymptotic behavior for small ε > 0 of multiple asymptotic solutions of the nonlinear boundary value problem
εu" + u’ - g(x,u) = 0, 0 < x < 1,
u’(0) - au(0)= A ≥ 0, a > 0,
u’(1) + bu(1) = B > 0, b > 0.
Formal techniques of singular perturbation theory clearly reveal the mechanism which controls the appearance of multiple solutions. Their existence is then established rigorously by iteration schemes and the so-called "shooting method" for ordinary differential equations
