Detecting Relevant Deviations From the White Noise Assumption for Non‐Stationary Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of detecting deviations from a white noise assumption in time series. Our approach differs from the numerous methods proposed for this purpose with respect to two aspects. First, we allow for non‐stationary time series. Second, we address the problem that a white noise test is usually not performed because one believes ...

Besov regularity for operator equations on patchwise smooth manifolds [PDF]

, 2014
We study regularity properties of solutions to operator equations on patchwise smooth manifolds $\partial\Omega$ such as, e.g., boundaries of polyhedral domains $\Omega \subset \mathbb{R}^3$. Using suitable biorthogonal wavelet bases $\Psi$, we introduce

Crafting the Ocean: The Geographies of Environmental World‐Making

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract The paper departs from existing analyses of ‘world making’, bringing cultural and environmental geographies into further conversation through linking theories of crafting and world‐making together, through the lens of the contemporary aquarium and nascent oceanic geographies.

Infinite Systems of Functional Equations and Gaussian Limiting Distributions [PDF]

Discrete Mathematics & Theoretical Computer Science, 2012
In this paper infinite systems of functional equations in finitely or infinitely many random variables arising in combinatorial enumeration problems are studied. We prove sufficient conditions under which the combinatorial random variables encoded in the

$S^6$ and the geometry of nearly K\"ahler $6$-manifolds

, 2017
We review results on and around the almost complex structure on $S^6$, both from a classical and a modern point of view. These notes have been prepared for the Workshop "(Non)-existence of complex structures on $S^6$" (\emph{Erste Marburger ...

Denoising Multi‐Color QR Codes and Stiefel‐Valued Data by Relaxed Regularizations

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT The handling of manifold‐valued data, for instance, plays a central role in color restoration tasks relying on circle‐ or sphere‐valued color models, in the study of rotational or directional information related to the special orthogonal group, and in Gaussian image processing, where the pixel statistics are interpreted as values on the ...

Many neighborly inscribed polytopes and Delaunay triangulations [PDF]

Discrete Mathematics & Theoretical Computer Science, 2014
We present a very simple explicit technique to generate a large family of point configurations with neighborly Delaunay triangulations. This proves that there are superexponentially many combinatorially distinct neighborly $d$-polytopes with $n$ vertices
