利用不动点指数理论和锥理论研究了Hammerstein非线性积分方程组正解的存在性,并将结果推广到由n个次线性积分方程组成的方程组上.
By using the fixed point index and cone theories,the existence of positive solutions for the systems of sublinear integral equations is studied,and the main results are generalized to study the existence of positive solutions for the systems of n sublinear integral equations.
