With Kuratowski's theorem, there is at least a criterion to use in discussing the nonplanarity of a graph. 有了库拉图夫斯基定理,在讨论一个图的非平面性时,至少就有了一个判别准则可供使用。
The Kuratowski convergence of distance graph and epigraph 距离函数,图和上图的Kuratowski收敛
This paper gives some results about the m-accumulation points, m-derived sets and m-dense in itself sets and suggests a group of axioms on the m-derived set operator, which are similar to the Kuratowski closure axioms. 本文给出关于m-聚点,m-导集以及m-自密集的若干结果,并提出了一组与Kurotowski闭包公理相类似的m-导集算子的公理。
By using the conditions of ( Kuratowski) measure of non compactness and the method of approximate, an existence theorem of the solution is obtained. 应用(Kuratowski)非紧性测度的条件和逼近方法,得到解的存在性定理。
