Historical basis and mathematical significance of Riemann surfaces Right. IMO for those who are interested in quick applications of the Abel-Jacobi theorem and are not prepared/motivated to study homology and cohomology theories, a classical exposition of the theory might work just fine. |

Are continuous self-bijections of connected spaces homeomorphisms? There is a thread on Mathoverflow devoted to a similar question: mathoverflow.net/questions/30661/… |

How can I find the derivative of $y = \ln [\ln(\ln(x^2 +1))]$? Are you familiar with the chain rule? |

Volumes of n-balls: what is so special about n=5? Yes, this is an analytic argument I referred to implicitly. I'd like to know if there is any geometry behind that. |

Volumes of n-balls: what is so special about n=5? Well, for an $n$-dimensional ball of radius $R$ we can consider the ratio $$\frac{V_n(R)}{R^n}.$$ This is a "dimensionless" quantity. |

Constructing a Cantor-like set by subtracting closed intervals Alternatively, the measure of the set will not depend on whether you subtract closed or open intervals since the difference is a countable sequence of endpoints, i.e. a measure zero set. |

Constructing a Cantor-like set by subtracting closed intervals You will end up with a set of measure $1-\alpha$ because the Lebesgue measure is $\sigma$-additive (countably additive). |

Domain of the Gamma function $t^{z-1}e^{-t}$ has a non-integrable singularity at $t=0$ when $\Re z\leq 0$. |

An orthonormal set cannot be a basis in an infinite dimension vector space? Thanks to everyone for the comments. I implicitly assumed that the space is complete. |

Proving that the sequence $F_{n}(x)=\sum\limits_{k=1}^{n} \frac{\sin{kx}}{k}$ is boundedly convergent on $\mathbb{R}$ The argument works for $x\neq 2\pi m$. |
