摘要
本文研究了非线性系统奇摄动问题:ε2y"-(x,y,y)=0,0<x<1,0<ε≤1,y(0)-py'(0)=A,p>0,y(1)=B,其中y,f,A,B为n维向量.在相应的假设下,利用代数型边界层函数,证明了该问题存在一个解y(x,ε),并利用微分不等式方法得到了其解的渐近估计.
The singularly perturbed nonlinear system ε2y'-f(x, y,y')=0, 0<x<1,0<ε≤1,y (0) -py' (0)=A,p>0,y(1)=B, where y,f,A , B are n-dimensional vectors is considered. Under the appropriate assumptions,using the algebraic boundary layer functions, the author proved that there exists a solution y(x,ε) and the estimation of y(x,ε) is obtained using the method of differential inequalities.
