    • Monoid valuations and value ordered supervaluations 

      [OWP-2011-17] Izhakian, Zur; Knebusch, Manfred; Rowen, Louis (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      We complement two papers on supertropical valuation theory ([IKR1], [IKR2]) by providing natural examples of m-valuations (= monoid valuations), after that of supervaluations and transmissions between them. The supervaluations ...

      Summation-by-parts (SBP) operators allow us to systematically develop energy-stable and high-order accurate numerical methods for time-dependent differential equations. Until recently, the main idea behind existing SBP ...
    • Multiple Bernoulli series and volumes of moduli spaces of flat bundles over surfaces 

      [OWP-2013-04] Baldoni, Maria Welleda; Boysal, Arzu; Vergne, Michèle (Mathematisches Forschungsinstitut Oberwolfach, 2013-03-14)
      Using Szenes formula for multiple Bernoulli series, we explain how to compute Witten series associated to classical Lie algebras. Particular instances of these series compute volumes of moduli spaces of flat bundles over ...

      [OWR-2017-17] (2017) - (26 Mar - 01 Apr 2017)
      High-dimensional problems appear naturally in various scientific areas. Two primary examples are PDEs describing complex processes in computational chemistry and physics, and stochastic/ parameter-dependent PDEs arising ...

      High-dimensional problems appear naturally in various scientific areas, such as PDEs describing complex processes in computational chemistry and physics, or stochastic or parameter-dependent PDEs leading to deterministic ...
    • 2204 - Multiscale Coupled Models for Complex Media: From Analysis to Simulation in Geophysics and Medicine 

      [OWR-2022-4] (2022) - (23 Jan - 29 Jan 2022)
      Many real-life applications require mathematical models at multiple scales, defined in domains with complex structures, some of which having time dependent boundaries. Mathematical models of this type are encountered in ...

    • The mystery of sleeping sickness – why does it keep waking up? 

      [SNAP-2015-015-EN] Funk, Sebastian (Mathematisches Forschungsinstitut Oberwolfach, 2015)

      A polynomial automorphism $F$ is called shifted linearizable if there exists a linear map $L$ such that $LF$ is linearizable. We prove that the Nagata automorphism $N:= (X-Y\Delta-Z\Delta^2,Y+Z\Delta,Z)$ where $\Delta=XZ+Y^2$ ...
