摘要
主要研究下面二阶脉冲三点边值问题y+q(t)=0,0<t<1,t≠t1,-Δy'|t=t1=I(y(t1)),y(0)=0,y(1)=ξy(c),0<ξ<1,0<c<1,通过构建格林函数的方法证明此系统存在唯一正解。
This paper mainly diseusses the three-point boundary value problem of second-order pulse {y"+q(t)0,0〈t〈1,t≠t1, -△y'1t=l1=1(y(t1)), y(0)=0,y(1)=ξ〈1,〈0〈c〈1}, proves that there is a unique positive solution for the system by Green function method.
