Singular perturbation solution of boundary-value problem for a secord-order differential-difference equation

  • Xu Jun-tao


In this paper, the method of two-variables expansion is used to construct boundary layer terms of asymptotic solution of the boundary-value problem for a second-order DDE. The n-order formal asymptotic solution is obtained and the error is estimated. Thus the existence of uniformly valid asymptotic solution is proved.
