    • Spherical Arc-Length as a Global Conformal Parameter for Analytic Curves in the Riemann Sphere 

      [OWP-2016-21] Gauthier, Paul Montpetit; Nestoridis, Vassili; Papadopoulos, Athanase (Mathematisches Forschungsinstitut Oberwolfach, 2016-11-11)
      We prove that for every analytic curve in the complex plane $\mathbb{C}$, Euclidean and spherical arc-lengths are global conformal parameters. We also prove that for any analytic curve in the hyperbolic plane, hyperbolic ...
    • Splitting Necklaces, with Constraints

      We prove several versions of Alon's "necklace-splitting theorem", subject to additional constraints, as illustrated by the following results. (1) The "almost equicardinal necklace-splitting theorem" claims that, without ...
    • Square wave periodic solutions of a differential delay equation 

      [OWP-2014-09] Ivanov, Anatoli F.; Verriest, Erik I. (Mathematisches Forschungsinstitut Oberwolfach, 2014-05-13)
      We prove the existence of periodic solutions of the differential delay equation $\varepsilon\dot{x}(t) + x(t)= f(x(t-1)), \varepsilon>0$ under the assumptions that the continuous nonlinearity $f(x)$ satisfies the negative ...

      [OWR-2019-22] (2019) - (05 May - 11 May 2019)
      The recent explosion of data that is routinely collected has led scientists to contemplate more and more sophisticated structural assumptions. Understanding how to harness and exploit such structure is key to improving the ...
    • 1339 - Statistical Inference for Complex Time Series Data 

      [OWR-2013-48] (2013) - (22 Sep - 28 Sep 2013)
      During recent years the focus of scientific interest has turned from low dimensional stationary time series to nonstationary time series and high dimensional time series. In addition new methodological challenges are coming ...
    • 1811 - Statistical Inference for Structured High-dimensional Models 

      [OWR-2018-12] (2018) - (11 Mar - 17 Mar 2018)
      High-dimensional statistical inference is a newly emerged direction of statistical science in the 21 century. Its importance is due to the increasing dimensionality and complexity of models needed to process and understand ...
    • 1004 - Statistical Issues in Prediction: what can be learned for individualized predictive medicine? 

      [OWR-2010-6] (2010) - (24 Jan - 30 Jan 2010)
      Error is unavoidable in prediction. And it is quite common, often sizable, and usually consequential. In a clinical context, especially when dealing with a terminal illness, error in prediction of residual life means that ...
    • 1925b - Statistical Methodology and Theory for Functional and Topological Data

    • Statistics and dynamical phenomena 

      [SNAP-2014-006-EN] Tong, Howell (Mathematisches Forschungsinstitut Oberwolfach, 2014)
      A friend of mine, an expert in statistical genomics, told me the following story: At a dinner party, an attractive lady asked him, "What do you do for a living?" He replied, "I model." As my friend is a handsome man, the ...
