摘要: 该文利用拓扑方法和锥理论研究下列Hammerstein非线性积分方程组

u(x)=∫G k(x,y)f(y,u(y),v(y)) dy,
v(x)=∫Gk(x,y)g(y,u(y),v(y)) dy.
在适当的条件下,证明了上述方程组非平解的存在性,并把所得结果应用于研究非线性
二阶常微分方程组边值问题的非平凡解的存在性.

关键词: 积分方程组, 锥, 不动点, 非平凡解

Abstract: In this paper, by using topological methods and cone theory, the authorstudies the system of nonlinear
Hammesrstein integral equations

u(x)=∫G kx,y)f(y,u(y),v(y)) dy,
v(x)=∫G k(x,y)g(y,u(y),v(y))dy,

The author proves the existence of nontrivial solutions of the above system under appropriate conditions. And the main results are applied
to study the existence of nontrivial solutions of boundary value problems for systems of nonlinear second order ordinary differential equations.

Key words: System of integral equations, Cone, Fixed point, Nontrivial solution.
