摘要
研究了一类二阶系统奇异边值问题非负解的存在唯一性,并在适当的条件下利用推广了的压缩映像原理,给出了该问题非负解的存在唯一性定理.
This paper studies the existence and uniqueness of nonnegative solution for a class of singular second--order systems boundary value problems. Using the popularized contraction mapping principle, the paper gives the existence and uniqueness theorem of nonnegative solution of this problem under some mild conditions.
