Distribution of a random walk on a directed line
Good point, but a closed approximation up to low order terms is fine, i.e. $P[X_2 = 1] = \frac{\ln n }{ n} + \frac{c}{n} + o\left(\frac{1}{n}\right)$. |

Distribution of a random walk on a directed line
Thanks, but this still doesn't seem like a closed form. If I take $\frac{d^t g_{nj}(z) }{ d z^t}$ at $z = 0$ then it still looks like an expansion over all possible paths. |

Approximation theory under $L_1$-error
Thank you, did you have a chance to look at these sources? Unfortunately, I can't find any preview online and my university library doesn't have them as well. |

Volume change under linear transformation
Thank you, Sergei! There is a specific reason, why the $L_1$-balls are important, rather than $L_\infty$-balls. However, because I am ultimately interested in some specific class of linear mappings, the combinatorial type is fixed and one can get a closed formula. |

Volume change under linear transformation
Thank you, but I am not sure I understand how can this be used to compute the $\mathcal{L}^m(f(S))$, which I am interested in. Also, shouldn't the formula have $\mathcal{H}^{n - m}$, rather than $\mathcal{H}^{m - n}$ on the left-hand side? |
