The Burau representation and shapes of polyhedra [PDF]
, 2023 We use a geometric approach to show that the reduced Burau representation specialized at roots of unity has another incarnation as the monodromy representation of a moduli space of Euclidean cone metrics on the sphere, as described by Thurston. Using the

Burau representation of braid groups and $q$-rationals [PDF]
, 2023 We establish a link between the new theory of $q$-deformed rational numbers and the classical Burau representation of the braid group $\mathrm{B}_3$. We apply this link to the open problem of classification of faithful complex specializations of this ...

The Burau representation is unitary
, 1984 A slight modification of the Burau representation of the braid group is shown to be unitary relative to an explicitly defined Hermitian form. This gives a partial answer to the problem of identifying the image of the Burau representation and provides a ...

Molecular Ecology, Volume 35, Issue 10, May 2026.ABSTRACT Effective population size (Ne), census size (Nc) and their ratio (Ne/Nc) are widely used indicators in conservation genetics, yet long‐term empirical data tracking of all three metrics over long time scales in wild populations remains rare. Using monitoring data from 1995 to 2020, we examined temporal dynamics of Ne, Nc and their relationship ...

Policy Innovation in Barcelona and Utrecht: The Role of Advocacy Coalitions in Multilevel Contexts
Politics &Policy, Volume 54, Issue 2, April 2026.ABSTRACT This article explores how policy innovation in local social policies emerges within a multilevel governance context. Drawing on the Advocacy Coalition Framework (ACF), it examines how beliefs, coalitions, and institutional arrangements interact across different political arenas—European, national/regional, and local—to foster innovative social

, 2007 11 pagesThe Burau representation enables to define many other representations of the braid group $B_n$ by the topological operation of ``cabling braids''. We show here that these representations split into copies of the Burau representation itself and of

Environmental DNA, Volume 8, Issue 2, March/April 2026.We measured a positive linear relationship between eDNA concentration and abundance for larval Delta Smelt (Hypomesus transpacificus) with N = 1 larva exceeding the limit of detection for the novel qPCR assay. Field experiments quantified the probability of detection for eDNA sampling methods at known abundances and distances from source. ABSTRACT Rare

Ecological Applications, Volume 36, Issue 1, January 2026.Abstract Major estuaries globally are experiencing fast‐paced changes in hydrology and ecosystem dynamics. However, connecting alteration of river flow regimes to estuarine fish population dynamics remains a challenge, partly due to the untested assumption that flow regimes, fish dynamics, and the resulting flow–ecology relationships are stationary (i ...

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract We assessed responses of Arctic Isochrysis sp. grown under a matrix of temperature (2°C vs. 6°C), light intensity (55 vs. 160 μmol photons m−2 s−1) and pCO2 (400 vs. 1000 μatm CO2). Next to acclimation parameters (growth rates, particulate and dissolved organic C and N, chlorophyll a content), we measured physiological processes in vivo ...
