摘要
利用上下解方法,证明了一类含间断项的二阶三点边值问题最大连续解和最小连续解的存在性,并完善和证明了已有的某些结果.
By using the upper and lower solution method, the existence of maximal and minimal coutinuous solutions for a class of two-order three-point boundary value problems with discontinuous terms is proved, and some well-known results are improved and proved .
