lower semicontinuous function meaning in Chinese

下半连续函数

Thus , the normality of space is conpletely characterized by lower semicontinuous function and upper semicontinous function
这样空间的正规性就完全可以用上半连续函数和下半连续函数来刻画。
Based on the " size " of the set of perturbed minimal points in the variational principle , the differentiability of lower semicontinuous functions is examined by means of approximation of the infconvolution sequence
摘要通过函数的下卷积函数列的逼近方法，在变分原理中从扰动最小值点集的“大小”入手，研究了下半连续函数的可微性。
