Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

River metabolism regimes across large environmental gradients
Limnology and Oceanography, Volume 70, Issue 9, Page 2718-2732, September 2025.Abstract Rivers process up to half of the terrestrial organic carbon before it reaches the oceans, playing an essential role in the global carbon cycle. However, little is known of the seasonal and regional patterns of riverine biological activity as most river ecosystem metabolism studies have been carried out at short spatial and temporal scales.

The minima of the geodesic length functions of uniform filling curves
Journal of the London Mathematical Society, Volume 111, Issue 4, April 2025.Abstract There is a natural link between (multi‐)curves that fill up a closed oriented surface and dessins d'enfants. We use this approach to exhibit explicitly the minima of the geodesic length function of filling curves that admit a self‐transverse homotopy equivalent representative such that all self‐intersection points, as well as all faces of the ...

Herbarium specimens reveal links between leaf shape of Capsella bursa‐pastoris and climate
American Journal of Botany, Volume 111, Issue 11, November 2024.Abstract Premise Studies into the evolution and development of leaf shape have connected variation in plant form, function, and fitness. For species with consistent leaf margin features, patterns in leaf architecture are related to both biotic and abiotic factors.

Classification conjectures for Leavitt path algebras
Bulletin of the London Mathematical Society, Volume 56, Issue 10, Page 3011-3060, October 2024.Abstract The theory of Leavitt path algebras is intrinsically related, via graphs, to the theory of symbolic dynamics and C∗$C^*$‐algebras where the major classification programs have been a domain of intense research in the last 50 years. In this article, we gather together current lines of research in the classification of Leavitt path algebras ...

Long‐term trends in mountain groundwater levels across Canada and the United States
Hydrological Processes, Volume 38, Issue 9, September 2024.Fifty‐four percentage of observation wells in mountain regions of Canada and the United States show statistically significant (p < 0.05) temporal trends in groundwater level (i.e., hydraulic head) over their period of record. Sixty‐nine percentage of significant trends was negative, indicating declining groundwater storage.

Topological recursion for Kadomtsev–Petviashvili tau functions of hypergeometric type
Journal of the London Mathematical Society, Volume 109, Issue 6, June 2024.Abstract We study the n$n$‐point differentials corresponding to Kadomtsev–Petviashvili (KP) tau functions of hypergeometric type (also known as Orlov–Scherbin partition functions), with an emphasis on their ℏ2$\hbar ^2$‐deformations and expansions.

Ecology, Volume 105, Issue 2, February 2024.Abstract Outbreaks of environmentally transmitted parasites require that susceptible hosts encounter transmission stages in the environment and become infected, but we also know that transmission stages can be in the environment without triggering disease outbreaks.

The spectrum of a twisted commutative algebra
Proceedings of the London Mathematical Society, Volume 128, Issue 1, January 2024.Abstract A twisted commutative algebra is (for us) a commutative Q$\mathbf {Q}$‐algebra equipped with an action of the infinite general linear group. In such algebras, the “GL$\mathbf {GL}$‐prime” ideals assume the duties fulfilled by prime ideals in ordinary commutative algebra, and so it is crucial to understand them.

Inhomogenous model of crossing loops and multidegrees of some algebraic varieties
, 2005 We consider a quantum integrable inhomogeneous model based on the Brauer algebra B(1) and discuss the properties of its ground state eigenvector. In particular we derive various sum rules, and show how some of its entries are related to multidegrees of ...
