Über die "Vorkurs-Brücke" in die Mathematik-Werkstatt
Zeitschrift für Hochschulentwicklung, 2014 Oftmals werden mit Vorkursen Brücken gebaut, durch welche der Weg zur Mathematik an Hochschulen bereitet werden soll. Wir stellen hier ein integriertes Konzept vor, das die Studierenden durch freiwillige Teilnahme an einem Vortest in einen jeweils ...

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 ...

polymake and Lattice Polytopes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 The $\mathtt{polymake}$ software system deals with convex polytopes and related objects from geometric combinatorics. This note reports on a new implementation of a subclass for lattice polytopes.

Towards Oblique Engagements With ‘Tipping Points’: A Critical Geography for Redirecting Debates
Transactions of the Institute of British Geographers, Volume 51, Issue 3, September 2026.ABSTRACT This intervention brings debates about tipping points into conversation with critical geographical thinking to suggest a more ‘oblique’ engagement with the concept. Such an approach is vital for rethinking the normative discourses and established imaginaries that dominate in the application of ‘tipping’ to understandings of environmental ...

Design und Erforschung von Lernumgebungen als Kern der Mathematikdidaktik
Beiträge zur Lehrerinnen- und Lehrerbildung, 1998 Wie jede andere Fachdidaktik kann auch die Mathematikdidaktik nur in interdisziplinärer Grenzüberschreitung betrieben werden, indem sie auf die Ergebnisse und Methoden der Mathematik, der Allgemeinen Didaktik, der Pädagogik und Psychologie zurückgreift.

Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 14244-14265, August 2026.ABSTRACT In this second part of our series of papers, we develop an abstract framework suitable for de Rham complexes that depend on a parameter belonging to an arbitrary Banach space. Our primary focus is on spectral perturbation problems and the differentiability of eigenvalues with respect to perturbations of the involved parameters. As a byproduct,

Finite‐Block Polynomial and Volterra Structure in Reservoir Computing
Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.ABSTRACT Reservoir computing is analyzed through the algebraic structure generated by finite‐width reservoirs on fixed input blocks. For linear and quadratic logistic activations, the induced input‐to‐state map admits an exact finite Volterra representation, yielding an explicit characterization of the associated hypothesis class.
