So you have found your way to our wiki. Here you can find and share the questions you have been asked during your oral examinations as a mathematics student of ETH Zürich. If you want to use LaTeX-Code use \( ... \) for inline math and $ ... $ for display mode. Here's an example:
$$ \sigma_1(n) \leq H_n + \exp (H_n) \log (H_n) $$
for all \( n \in \mathbf{N} \) and where \( H_n = \sum_{k = 1}^n \frac{1}{k} \) and $\sigma_1 (n) = \sum_{d \mid n} d.
