(De)composing sociality: Disentangling individual‐specific from dyad‐specific propensities to interact

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 963-978, March 2026.
Abstract In group‐living animals, relationships between group members are often highly differentiated. Some dyads can maintain strong and long‐lasting relationships, while others are only connected by weak or fleeting ties. More and more studies show that aspects of social relationships are related to reproductive success and survival.

Certain invariant subspaces for operators with rich eigenvalues

International Journal of Mathematics and Mathematical Sciences, 1991
For a connected open subset Ω of the plane and n a positive integer, let Bn(Ω) be the space introduced by Cowen and Douglas. In this article we study the spectrum of restrictions of T in order to obtain more information about the invariant subspaces of T.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Bergman kernels of monomial polyhedra

Journal of Mathematical Analysis and Applications
The Bergman kernels of monomial polyhedra are explicitly computed. Monomial polyhedra are a class of bounded pseudoconvex Reinhardt domains defined as sublevel sets of Laurent monomials. Their kernels are rational functions and are obtained by an application of Bell's transformation formula.

Weighted reproducing kernels in Bergman spaces.

Michigan Mathematical Journal, 1994
A major inspiration for this paper is the factorization theory developed by \textit{H. Hedenmalm} [J. Reine Angew. Math. 422, 45-68 (1991; Zbl 0734.30040)] for the standard Bergman space \(A^2\), and later generalized to the Bergman space \(A^2\) by \textit{P. Duren}, \textit{D. Khavinson}, \textit{H. S. Shapiro} and \textit{C. Sundberg} [Pac. J. Math.

The weak (1,1) boundedness of Fourier integral operators with complex phases

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract Let T$T$ be a Fourier integral operator of order −(n−1)/2$-(n-1)/2$ associated with a canonical relation locally parametrised by a real‐phase function. A fundamental result due to Seeger, Sogge and Stein proved in the 90's gives the boundedness of T$T$ from the Hardy space H1$H^1$ into L1$L^1$. Additionally, it was shown by T.

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Vanishing Bergman Kernels on the Disk [PDF]

The Journal of Geometric Analysis, 2017
We discuss topics related to zeroes of the Bergman kernels, and present a method for generating Bergman kernels with arbitrarily, but finitely, many zeroes. It is also shown that a Bergman kernel induced by a radial weight on the unit disk cannot have infinitely many zeroes.

Using Behavioral Science to end the Tropical Forest Wild Meat Crisis, illustrated by a case example from Central Africa

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Abstract In tropical forests today, hunting for food and income remains largely unsustainable, with adverse implications for biodiversity, ecological services, and human wellbeing. Even though our scientific knowledge of the issue has improved greatly in recent years, the situation on the ground has not. This Perspective presents our opinions and ideas
