A 100 years old conjecture states that every closed simple curve in the plane (Jordan curve) contains 4 vertices of a square.
It was proved for smooth curves using standart topological methods. The general case, however, is still open and some geometric intuition is likely required to make any progress.
In the talk I will highlight some of the known results. I will also talk about the more general question – which quadrilaterals can be inscribed in any curve?
Part of the talk is joint work with A. Akopyan.
