$L^0$ is just a notation to refer to the weakness of the topology of convergence in measure. It is not locally bounded but is metrizable if the underlying measure space is non-atomic and …
L0范数及数据压缩感知 - 知乎 - 知乎专栏
为了描述稀疏性,我们引入一个函数,称为“ l_ {0} 范数”。 它是向量 x 中非零元素的数量,记作: \lVert x \rVert_ {0} =\#\ {i|x (i)\ne 0\} 这里的 \# 表示计数,对后面集合中元素个数统计。 所以, …

Zero power zero and $L^0$ norm - Mathematics Stack Exchange
$L^0$ norm is defined as: $$ L^p = (\sum_i|x_i|^p)^{(1/p)} $$ with $p=0$. Now this is argued to count the number nonzero elements in a vector $\textbf{x}$. If this is taken to be true, then the …
