Colloquium: Benjamin Matschke, On inscribing quadrilaterals into Jordan curves
Wednesday, 28. February 2018, 13:30 - 14:30
Benjamin Matschke's Talk:
 

On inscribing quadrilaterals into Jordan curves
 

Abstract: Talk is about an open problem in plane geometry due to Otto Toeplitz (1911) and
several related problems about inscribing and circumscribing polytopes in and around manifolds.
Toeplitz originally asked whether every Jordan curve contains the four vertices of a square. Over
the years it was proved in various special cases, nonetheless it remains an open problem in its full
generality. We will also mention recent progress on the classification of quadrilaterals that can be
inscribed in convex curves.
