Abstract: | In this paper we study initial value problems on the infinite interval: where x, f∈Em, y, g∈En,εare real small positive parameters,0≤t<+∞. On condition that gy(t) is nonsingular and under other assumptions, we have proved that there areserial (k+m*) -dimensionalmanifolds {SR(ε)}∈m+n such that (1.1) degenerates regularly provided(ξ(ε),η(ε))∈SR(ε). Besides, the R-order asymptotic expansions of solutions are constructed, and their errors are estimated. |
