摘要
在以往对二阶半正边值问题的研究中,非线性项的限制是比较高的,如要求连续或者单调,本文将非线性项 f,g 的条件放宽,研究其同为超线性或者其中一个为超线性,一个为次线性,且允许下方无界的情况下,利用锥压缩与锥拉伸定理,讨论其正解的存在性。
In formerly to two step half boundary value problem research in, a non--linear limit was quite high, if requests continuously or monotonous, in this article, we the non--linear item off, g condition relaxation, study it with for the ultralinear or are the ultralinear, one is a sublinear, also underneath the permission does not have in the situation, stretches the theorem using the awl compression and the awl, discussed its normal solution existence.
