Isn't this asking the same as this? Jul 30 comment Is proving $m(E) < \epsilon, \forall \epsilon > 0$ equivalent to prove $m(E) = 0$? @DavidC.Ullrich That looks like an answer. Jul 30 comment Set-theoretic equality The overlining is for the complementary set? Jul 28 comment Residue integral: $\int_{- \infty}^{+ \infty} \frac{e^{ax}}{1+e^x} dx$ with $0 \lt a \lt 1$. @tacos_tacos_tacos here is the same integral calculated using a rectangular contour.

Jul 26 comment Is there a proof for the maximum principle without the Cauchy integral theorem? @DanielFischer That's an answer :-) Jul 26 comment A question about complex integration of $\frac{1}{p(z)}$ This is perfectly fine. And the reason why both integrals are equal is either by residues theorem or noting that those circles are homotopic. Jul 26 comment Geometric mean never exceeds arithmetic mean Which is in here Jul 26 comment $|g(x)| \leq K \int_a^x|g| \ \ \forall x \in I$ See this answer. Jul 25 comment Prove that a subset of a separable set is itself separable That's not the case, $d(x_i,e_{(i,j)})\lt r_j$. And that's because each $e_{(i,j)}$ is choose to be a point of $B(x_i,r_j)$. Jul 25 revised Prove that a subset of a separable set is itself separable Being consistent with earlier notation.
