摘要
研究在强稳定条件下的具有两个小参数的二阶微分方程的边值问题{εy″=f(t,y,y′,ε,μ),a<t<by(a,ε,μ)=A(ε,μ),y(b,ε,μ)=B(ε,μ)的奇异摄动现象.
In this paper, we research the singular perturbation for boundary value problem of second order differential equation with two small parameter as following:
{εy″=f(t,y,y′,ε,μ),a〈t〈b
y(a,ε,μ)=A(ε,μ),y(b,ε,μ)=B(ε,μ)
under the condition of strong stability.
