    • How big is my slice of cheese? 

      [SNAP-2026-006-EN] Meroni, Chiara (Mathematisches Forschungsinstitut Oberwolfach, 2026-05-19)
      In this snapshot, we introduce the study of slices of polytopes – geometric shapes with flat sides – and examine the area of these slices. This is connected to combinatorics and polynomials and is surprisingly complex, ...

    • Triangulations in geometry: from Ptolemy to Teichmüller 

      [SNAP-2026-004-EN] Pressland, Matthew (Mathematisches Forschungsinstitut Oberwolfach, 2026-02-27)
      Ptolemy's theorem is a classical result from ancient Greek mathematics, concerning the lengths of sides and diagonals of a polygon drawn in a circle. In this snapshot, I will explain why this theorem is still important ...
