| Research Abstract |
We studied a boundary value problem of differential difference equations with many time lags in a real domain. A numerical process of constructing approximate solutions of was obtained by the method of Galerkin's procedure based 03 Chebysher polynomials.
Moreover an existence theorem was proved for our boudary value probrem. It said that one could always assure the existence of a Unique exact solution in the meighborhood of the obtaind approximate solutions by checking several conditions on them. Further it gave a method to obtain the error bounds of the approximate solutions. We also proved that for an isolated solution there existed an approximate solution accurately in the sense of uniform norm as it was desired by computing finite Chebysher series.
