2	Pullback of a vector field under a surjective submersion.
1	Doubt about pushforwards
1	If $A\subseteq\mathbb{R}$ and $\lambda^*(A)>0$ then $A$ contains a measurable subset that is not Borel.
1	How to prove that a logarithmic divergence implies a measure has no atoms?
1	Show that for any $E=E_1 \cup E_2$, $μ(E)=μ^∗(E_1)=μ^∗(E_2)$

4	Why $\lim_{r\to 1^-} \int_0^{2\pi}\ln(\|f(re^{i\vartheta})\|)d\vartheta=-\infty$?
2	An application of Hahn-Banach to analytic functions
2	Surjective holomorphic map from a domain to $\mathbb{C}$
2	Is Riesz Lemma really necessary?
2	Proof verification: if $f:\Omega\to \Omega$ has two fixed points, is conformal and $f^n=\text{Id}$
