    • Spherical Subgroups in Reductive Algebraic Groups 

      [OWP-2026-03] Knop, Friedrich; Röhrle, Gerhard (Mathematisches Forschungsinstitut Oberwolfach, 2026-07)
      In [KR15], we determined all spherical affine homogeneous varieties for simple algebraic groups in arbitrary characteristic. The present paper extends this classification to semisimple groups. This generalizes work done ...

    • Transverse Foliations for Two-Degree-of-Freedom Mechanical Systems 

      [OWP-2026-02] de Paulo, Naiara V.; Kim, Seongchan; Salomão, Pedro A. S.; Schneider, Alexsandro (Mathematisches Forschungsinstitut Oberwolfach, 2026-03)
      We investigate the dynamics of a two-degree-of-freedom mechanical system for energies slightly above a critical value. The critical set of the potential function is assumed to contain a finite number of saddle points. As ...

    • On Constructing Small Subgraphs in the Budget-Constrained Random Graph Process 

      [OWP-2026-01] Antoniuk, Sylwia; Espuny Díaz, Alberto; Petrova, Kalina; Stojaković, Miloš (Mathematisches Forschungsinstitut Oberwolfach, 2026-02)
      Consider the budget-constrained random graph process introduced by Frieze, Krivelevich and Michaeli, where each time an edge is offered through the (standard) random graph process we must irrevocably decide whether to ...
