摘要
研究了带小参数的一类三阶边值问题:εx'n=f(t,x,x',ε),x(0),x(0)=A,x'(0)=x'(1),xn(0)=xn(1),得到解的存在性和渐进估计.
This article shows the existence and asymptotic estimate solutions of singularly perturbed boundary value problems for a class of third order nonlinear differential equations: εxn'=f(t, x, x', ε), x(0) = A, x'(0) = x'(1), xn(0) = xn(l) by upper and lower solutions.
