摘要
研究一阶奇异半正耦合微分方程组周期边值问题.对该方程组不同的半正形式,建立半正耦合方程组周期边值问题解的存在性的充分条件,定理的证明依赖于Schauder不动点定理。
The existence of solutions to periodic boundary value problems of the first order non - autonomous singular semipositone coupled systems pied systems with some type of semipositone is is investigated, and the existence of solutions to the couestablished. The proof relies on Schauder' s fixed point theorem.
