Altman定理的改进及其应用

An Improvement of Altman's Theorem and its Applications

文章利用拓扑度理论进一步改进了Altman定理,得到了凝聚映象和p1 紧映象的一些新不动点,并且将此结果应用于YPыCOH积分方程,解决了它的解的存在性问题。

Altman's Theorem is further improved and some new fixes-point theorems for condensing mapping or P 1-compact mappings are set up by topology theory.The theorems are applied to YPъICOH integral equations and new results are obtained
