摘要
研究了一类三阶奇摄动边值问题εx =f(t,x,x ,ω(ε)x",ε),x(0)=A,x (0)=x (1),x"(0)=x"(1),得到了解的存在性和渐近估计.
Singularly perturbed boundary value problems for a class of t hird order nonlinear differentian equations: εx=f(t,x,x ,(ε)x',ε),x(0)=A,x (0)=x (1),x'(0)=x'(1) is studied by upper and lower solutions,the existence and asymptotic estimates of solution are obtained.
