compact mapping meaning in English
紧映射
Examples
- A fixed point theory about limitation map of compact maps sequence
一个关于紧映射序列极限的不动点定理 - We then prove that the em algorithm becomes a compact map in certain neighborhood of a consistent solution when a measure of the average overlap of gaussians in the mixtures is small enough and the sample size is large enough
我们证明了高斯混合体em算法在混合密度的重叠度很小时在其样本真解相一致的解的一个邻域内是一个压缩映射。 - With the usage of degree theory in [ 1 ] , calculating indices of fixed points of compact maps in cones of [ 2 - 10 ] and combining with bifurcation theories [ 11 - 19 ] , maximum principles [ 17 ] [ 19 ] , lower - upper solutions methods [ 20 - 22 ] and spectrum analysis of operators [ 23 - 24 ] , we get some results of the coexistence solutions for modell in the first section . the results can be seen extensions of [ 7 ] [ 23 ]
利用文献[ 1 ]中度理论、 [ 2 - 10 ]中锥映象不动点指数方法，并结合分歧理论，极值原理，上下解方法和算子谱分析等，在文中第一部分讨论了其平衡解的存在性，部分推广了文献[ 7 ] [ 23 ]的结论。 - Fairly important covers have point - countable bases , weakly bases , k - networks , sequence - neighbourhood networks and so on . fairly important mappings have quotient s - mappings , closed s - mappings , open mappings , open - and - closed mappings , com - pact - and - open mappings , perfect mappings , countable bi - quotient mappings , compact mappings
比较重要的覆盖有点可数基，弱基， k网，序列邻域网；比较重要的映射有商s映射，闭s映射，开映射，开闭映射，紧开映射，完备映射，可数双商映射，紧映射。
