1) third-order two-point semipositive
三阶二点半正
1.
By using the fixed point theory in cones,we obtained the existence of positive solutios for the third-order two-point semipositive boundary value problems in which nonlinearity f(t,u)does not have to be continuous and lower bounded but only have to meet Carathéodory s conditions.
本文利用锥上的不动点定理,不要求非线性项f(t,u)连续且下方有界,在f满足Carathéodory条件下,证明了一类三阶二点半正边值问题正解的存在性。
2) third-order two-point semipositone systems

4) two order and three points formula
二阶三点公式
6) third-order semipositone ODE
三阶半正常微分方程
