• The 4-Sample Theorem on planar graphs 

      [SNAP-2026-005-EN] Améndola, Carlos; Kahle, Thomas (Mathematisches Forschungsinstitut Oberwolfach, 2026-04-10)
      The famous 4-Color Theorem from graph theory states that the vertices of any planar graph can be colored with four colors, so that no neighboring vertices have the same color. The 4-Sample Theorem from algebraic statistics ...
    • Do the rich get richer? Mathematical models for real-world networks 

      [SNAP-2026-010-EN] Lodewijks, Bas (Mathematisches Forschungsinstitut Oberwolfach, 2026-09-11)
      Networks can be found all around us. From the friendships we form, both in person and online, to the websites we visit on the Internet, and the telephones we use to send messages and make phone calls. Understanding the ...
    • Game-theoretic statistics 

      [SNAP-2026-009-EN] Shafer, Glenn (Mathematisches Forschungsinstitut Oberwolfach, 2026-09-11)
      Statistical modelling is the art of connecting abstract models with scientific or practical questions, so that the models' probabilities throw light on these questions. Standard statistical theory summarizes the results ...
