    • Domain-Scaled Regular Variation: Mathematical Foundations for a New Tail Process 

      [OWP-2025-02] Strokorb, Kirstin; Oesting, Marco; De Fondeville, Raphaël (Mathematisches Forschungsinstitut Oberwolfach, 2025-02)
      Threshold exceedances of stochastic processes in space and time often appear to be more localized the more extreme they are. While classical regularly varying stochastic processes cannot model this effect, we introduce an ...

    • Generalized Bose-Einstein Condensation in the Kac-Luttinger Model 

      [OWP-2025-06] Boccato, Chiara; Kerner, Joachim; Pechmann, Maximilian; Spitzer, Wolfgang (Mathematisches Forschungsinstitut Oberwolfach, 2025-07)
      In this article, we prove generalized Bose–Einstein condensation (BEC) at zero temperature in the random Kac–Luttinger model for repulsive two-particle interactions that are scaled suitably in the limit of large volume. ...

    • On Angular Momentum Algebras and their Relations 

      [OWP-2025-08] Calvert, Kieran; de Martino, Marcelo; Oste, Roy (Mathematisches Forschungsinstitut Oberwolfach, 2025-08)
      In this paper, we study the centraliser of $\mathfrak{osp}(1|2)$, denoted the total angular momentum algebra (TAMA), in the Weyl Clifford algebra. The TAMA extends the angular momentum algebra (AMA), which arises as the ...

    • Parabolic Normalizers in Finite Coxeter Groups as Subdirect Products 

      [OWP-2025-10] Douglass, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (Mathematisches Forschungsinstitut Oberwolfach, 2025-09)
      We revisit the structure of the normalizer $N_W(P)$ of a parabolic subgroup $P$ in a finite Coxeter group $W$, originally described by Howlett. Building on Howlett's Lemma, which provides canonical complements for reflection ...

    • Quadratically Enriched Plane Curve Counting via Tropical Geometry 

      [OWP-2025-03] Jaramillo Puentes, Andrés; Markwig, Hannah; Pauli, Sabrina; Röhrle, Felix (Mathematisches Forschungsinstitut Oberwolfach, 2025-02)
      We prove that the quadratically enriched count of rational curves in a smooth toric del Pezzo surface passing through $k$-rational points and pairs of conjugate points in quadratic field extensions $k\subset k(\sqrt{d_i})$ ...
