A: Algebraic geometry examples

PetyaI know the following example from Kontsevich. Not sure it is suitable to your course, but I like it. Consider a space of closed 6-edges polygonal lines in Euclidean ${\mathbb R}^3$ such that each edge has length $1$ and each angle between subsequent edges is the right angle. The problem is to co...
