    • 1744b - Copositivity and Complete Positivity 

      [OWR-2017-52] Workshop Report 2017,52 (2017) - (29 Oct - 04 Nov 2017)
      A real matrix $A$ is called copositive if $x^TAx \ge 0$ holds for all $x \in \mathbb R^n_+$. A matrix $A$ is called completely positive if it can be factorized as $A = BB^T$ , where $B$ is an entrywise nonnegative matrix. ...

    • 1728 - Dynamische Systeme 

      [OWR-2017-32] Workshop Report 2017,32 (2017) - (09 Jul - 15 Jul 2017)
      This workshop continued the biannual series at Oberwolfach on Dynamical Systems that started as the “Moser–Zehnder meeting” in 1981. The main themes of the workshop are the new results and developments in the area of ...

    • 1751 - Mathematical Instruments between Material Artifacts and Ideal Machines: Their Scientific and Social Role before 1950 

      [OWR-2017-58] Workshop Report 2017,58 (2017) - (17 Dec - 23 Dec 2017)
      Since 1950, mathematicians have become increasingly familiar with the digital computer in their professional practice. Previously, however, many other instruments, now mostly forgotten, were commonly used to compute numerical ...

    • 1724 - Nonlinear Waves and Dispersive Equations 

      [OWR-2017-27] Workshop Report 2017,27 (2017) - (11 Jun - 17 Jun 2017)
      Nonlinear dispersive equations are models for nonlinear waves in a wide range of physical contexts. Mathematically they display an interplay between linear dispersion and nonlinear interactions, which can result in a wide ...

    • 1740 - Spectral Structures and Topological Methods in Mathematical Quasicrystals 

      [OWR-2017-46] Workshop Report 2017,46 (2017) - (01 Oct - 07 Oct 2017)
      The mathematical theory of aperiodic order grew out of various predecessors in discrete geometry, harmonic analysis and mathematical physics, and developed rapidly after the discovery of real world quasicrystals in 1982 ...
