A closed discrete curve \(\gamma\) is map from a discrete circle \(\mathfrak S_n^1 =\{z\in\mathbb C \mid z^n = 1\}\), \(n\in \mathbb N\), into some space \(\mathrm M\). In some situations it is more convenient to consider the discrete circle just as \(\mathbb Z/n\mathbb Z\),\[\mathbb … Continue reading Tutorial 3: Framed Closed Curves
