Treewidth, crushing, and hyperbolic volume [PDF]
, 2019 We prove that there exists a universal constant $c$ such that any closed hyperbolic 3-manifold admits a triangulation of treewidth at most $c$ times its volume.

The Heegaard genus of bundles over S^1 [PDF]
, 2007 This paper explores connections between Heegaard genus, minimal surfaces, and pseudo-Anosov monodromies. Fixing a pseudo-Anosov map phi and an integer n, let M_n be the 3-manifold fibered over S^1 with monodromy phi^n.

On the automorphism groups of hyperbolic manifolds [PDF]
, 1999 We show that there does not exist a Kobayashi hyperbolic complex manifold of dimension $n\ne 3$, whose group of holomorphic automorphisms has dimension $n^2+1$ and that, if a 3-dimensional connected hyperbolic complex manifold has automorphism group of ...

The stable subset of a univalent self-map
, 2015 We give a complete description of the stable subset (the union of all backward orbit with bounded step) and of the pre-models of a univalent self-map $f: X\to X$, where $X$ is a Kobayashi hyperbolic cocompact complex manifold, such as the ball or the ...

Impact Plasma Amplification of the Ancient Mercury Magnetic Field
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Plant Species Biology, Volume 41, Issue 3, May 2026.Sasa species (Poaceae: Bambusoideae) are generally considered monocarpic mass flowering plants. Although seedling regeneration after small‐scale flowering has been largely overlooked, we demonstrated that some seedlings of Sasa veitchii var. tyugokuensis derived from small‐scale flowering survived for 11 years.

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Eight lectures on Oka manifolds [PDF]
, 2015 Over the past decade, the class of Oka manifolds has emerged from Gromov's seminal work on the Oka principle. Roughly speaking, Oka manifolds are complex manifolds that are the target of "many" holomorphic maps from affine spaces.

Global Change Biology, Volume 32, Issue 4, April 2026.Across four continents, we investigated how temperature controls the productivity of high mountain vegetation. We found that the productivity of plants growing close to the ground (< 1 m) tends to be controlled by highly localised “microclimate” temperatures, while the productivity of trees was strongly linked to broader‐scale temperatures.
