Obstructing Anosov flows on cusped 3‐manifolds

Bulletin of the London Mathematical Society, EarlyView.
Abstract Using results relating taut foliations, Heegaard–Floer homology and pseudo‐Anosov flows, we find cusped hyperbolic 3‐manifolds which are not the non‐singular part of a pseudo‐Anosov flow. In particular, we find the first examples of cusped hyperbolic 3‐manifolds not admitting veering triangulations, confirming a conjecture of S. Schleimer.

On the Zoll deformations of the Kepler problem

Bulletin of the London Mathematical Society, EarlyView.
Abstract A celebrated result of Bertrand states that the only central force potentials on the plane with the property that all bounded orbits are periodic are the Kepler potential and the potential of the harmonic oscillator. In this paper, we complement Bertrand's theorem showing the existence of an infinite‐dimensional space of central force ...

Rural Farmer‐Managed Wetland Agroecosystems Promote Climate Resilience in Semi‐Arid Savannah: Case of Nyororo Wetland, Mberengwa District, Zimbabwe

Climate Resilience and Sustainability, Volume 4, Issue 1, June 2025.
Changes in wetland size and increased drought frequency influenced wetland cultivation, groundwater depletion and the proliferation of invasive alien floral species. Building anticipatory actions through ecosystem‐based adaptation, anticipatory actions and seasonal livelihoods enhances agroecosystem resilience.
