次线性的 meaning in Chinese
sublinear
Examples
- A necessary and sufficient condition is given in paper [ 16 ] for the sublinear case by the method of upper and lower solution and pontrjagin maximum principle . but the superlinear results are spare because of the essential difference between the superlinear case and the sublinear case . in section two , we gave a necessary and sufficient condition for the superlinear case
对于四阶奇异微分方程边值问题有不少研究成果， o ’ regan [ 10 ]中利用拓扑横截定理给出了其解存在的充分条件，文献[ 16 ]则利用上下解方法和极大值原理给出了问题在次线性情形下正解存在的充分必要条件，由于超线性与次线性的本质区别，使得超线性的研究结果相对较少，本文第二节则致力于给出一类四阶超线性常微分方程奇异边值问题正解存在的充分必要条件
