The m-step solvable anabelian geometry of number fields
(De Gruyter, 25 June 2022)Given a number field K and an integer m≥0, let Km denote the maximal m-step solvable Galois extension of K and write GKm for the maximal m-step solvable Galois group Gal(Km/K) of K. In this paper, we prove that the isomorphy ... -
Compounding Heatwave‐Extreme Rainfall Events Driven by Fronts, High Moisture, and Atmospheric Instability
(American Geophysical Union (AGU) / Wiley, 28 October 2023)Heatwaves have been shown to increase the likelihood and intensity of extreme rainfall occurring immediately afterward, potentially leading to increased flood risk. However, the exact mechanisms connecting heatwaves to ... -
On insoluble transitive subgroups in the holomorph of a finite soluble group
(Elsevier, 5 October 2023)A question of interest both in Hopf-Galois theory and in the theory of skew braces is whether the holomorph Hol(N) of a finite soluble group N can contain an insoluble regular subgroup. We investigate the more general ... -
Simulating increased permafrost peatland plant productivity in response to belowground fertilisation using the JULES land surface model
(MDPI, 5 May 2022)Several experimental studies have shown that climate-warming-induced permafrost thaw releases previously unavailable nitrogen which can lower nitrogen limitation, increase plant productivity, and counteract some of the ... -
Zonostrophic instabilities in magnetohydrodynamic Kolmogorov flow
(Taylor and Francis, 6 November 2023)A classic stability problem relevant to many applications in geophysical and astrophysical fluid mechanics is that of Kolmogorov flow, a unidirectional purely sinusoidal velocity field written here as u=(0,sinx) in the ...
