    • 2351 - Arbeitsgemeinschaft: QFT and Stochastic PDEs 

      [OWR-2023-59] (2023) - (17 Dec - 22 Dec 2023)
      Quantum field theory (QFT) is a fundamental framework for a wide range of phenomena is physics. The link between QFT and SPDE was first observed by the physicists Parisi and Wu (1981), known as Stochastic Quantisation. ...

    • 0818 - Atomistic Models of Materials: Mathematical Challenges 

      [OWR-2008-21] (2008) - (27 Apr - 03 May 2008)
      The contributions in this report, written by leading mathematicians and materials scientists, summarize recent progress and main mathematical challenges in the exciting and fast growing interdisciplinary field of atomistic ...

    • 1545a - Mini-Workshop: Friezes 

      [OWR-2015-48] (2015) - (01 Nov - 07 Nov 2015)
      Frieze patterns were introduced in the early 1970s by Coxeter. They are infinite arrays of numbers in which every four neighbouring entries always satisfy the same arithmetic relation. Amazingly, friezes appear in many ...

    • 0518a - Mini-Workshop: Numerical Upscaling: Theory and Applications 

      [OWR-2005-20] (2005) - (01 May - 07 May 2005)
      Numerical upscaling is often the only way in which various multiscale problems can be handled. Numerics related to solving auxiliary problems appearing in asymptotic homogenization, as well as numerical treatment of ...

    • Non-stationary multivariate subdivision: joint spectral radius and asymptotic similarity 

      [OWP-2013-20] Charina, Maria; Conti, Costanza; Guglielmi, Nicola; Protasov, Vladimir (Mathematisches Forschungsinstitut Oberwolfach, 2013-10-29)
      In this paper we study scalar multivariate non-stationary subdivision schemes with a general integer dilation matrix. We present a new numerically efficient method for checking convergence and Hölder ...

    • On periodic solutions and global dynamics in a periodic differential delay equation 

      [OWP-2014-08] Ivanov, Anatoli F.; Trofimchuk, Sergei I. (Mathematisches Forschungsinstitut Oberwolfach, 2014-05-13)
      Several aspects of global dynamics and the existence of periodic solutions are studied for the scalar differential delay equation $x'(t) = a(t)f(x([t-K]))$, where $f(x)$ is a continuous negative feedback function, $x \cdot ...

    • 1006a - Optimal Constants in the Theory of Sobolev Spaces and PDEs 

      [OWR-2010-8] (2010) - (07 Feb - 13 Feb 2010)
      Recent research activities on sharp constants and optimal inequalities have shown their impact on a deeper understanding of geometric, analytical and other phenomena in the context of partial differential equations and ...
