    • On the Complexity of Epimorphism Testing with Virtually Abelian Targets 

      [OWP-2025-01] Elder, Murray; Shen, Jerry; Weiss, Armin (Mathematisches Forschungsinstitut Oberwolfach, 2025-01)
      Friedl and Löh (2021, Confl. Math.) prove that testing whether or not there is an epimorphism from a finitely presented group to the direct product of an abelian and a finite group, or to a virtually cyclic group, is ...

    • When Alcoved Polytopes Add 

      [OWP-2025-04] Early, Nick; Kühne, Lukas; Monin, Leonid (Mathematisches Forschungsinstitut Oberwolfach, 2025-04)
      Alcoved polytopes are characterized by the property that all facet normal directions are parallel to the roots ei−ej. Unlike other prominent families of polytopes, like generalized permutahedra, alcoved polytopes are ...
