• Multiparameter singular integrals on the Heisenberg group: uniform estimates 

  Vitturi, Marco; Wright, James (American Mathematical Society, 2020-05-26)

  We consider a class of multiparameter singular Radon integral operators on the Heisenberg group H-1 where the underlying submanifold is the graph of a polynomial. A remarkable difference with the euclidean case, where ...
• Slow-fast dynamics in a chaotic system with strongly asymmetric memristive element 

  Birkoben, Tom; Drangmeister, Moritz; Zahari, Finn; Yanchuk, Serhiy; Hövel, Philipp; Kohlstedt, Hermann (World Scientific, 2020-06)

  We investigate the effect of a memristive element on the dynamics of a chaotic system. For this purpose, the chaotic Chua’s oscillator is extended by a memory element in the form of a double-barrier memristive device. The ...
• Mass transport for Pollard waves 

  Kluczek, Mateusz; Stuhlmeier, Raphael (Taylor & Francis Group, 2020-06-19)

  We provide an in-depth exploration of the mass-transport properties of Pollard's exact solution for a zonally propagating surface water-wave in infinite depth. Without resorting to approximations we discuss the Eulerian ...
• Border-collision bifurcations in a driven time-delay system 

  Ryan, Pierce; Keane, Andrew; Amann, Andreas (AIP Publishing, 2020-02-07)

  We show that a simple piecewise-linear system with time delay and periodic forcing gives rise to a rich bifurcation structure of torus bifurcations and Arnold tongues, as well as multistability across a significant portion ...
• Interplay between competitive and cooperative interactions in a three-player pathogen system 

  Pinotti, Francesco; Ghanbarnejad, Fakhteh; Hövel, Philipp; Poletto, Chiara (Royal Society, 2020-01-22)

  In ecological systems, heterogeneous interactions between pathogens take place simultaneously. This occurs, for instance, when two pathogens cooperate, while at the same time, multiple strains of these pathogens co-circulate ...
