Subspaces of $L_p([0,1])$ whose unit ball is compact for the topology of convergence in measure

No, it does not: otherwise, the given closed subspace $V$ would be a subspace of $L^0$ (the space of measurable functions, metrised with the convergence in measure) whose unit ball would be compact, a …

Approximation of the radon-derivative

Here some references that show that (surprisingly!) the result you stated is wrong if $\liminf$ is replaced by $\limsup$ and $X=\mathbb{R}^2$. More precisely, if $\nu$ is the Lebesgue measure on the …
