Brauer groups of Quot schemes [PDF]

Michigan Mathematical Journal, 2015
Let $X$ be an irreducible smooth complex projective curve. Let ${\mathcal Q}(r,d)$ be the Quot scheme parametrizing all coherent subsheaves of ${\mathcal O}^{\oplus r}_X$ of rank $r$ and degree $-d$. There are natural morphisms ${\mathcal Q}(r,d) \longrightarrow \text{Sym}^d(X)$ and $\text{Sym}^d(X) \longrightarrow \text{Pic}^d(X)$.

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

Journal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

The Swanscombe fossil at 90: revisiting its phylogeny, taxonomy, and place in human origins Le fossile de Swanscombe, 90 ans après : retour sur sa place phylogénique, taxonomique et dans les origines de l'humanité

Journal of the Royal Anthropological Institute, EarlyView.
The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

Brauer groups for commutative S-algebras [PDF]

, 2012
We investigate a notion of Azumaya algebras in the context of structured ring spectra and give a definition of Brauer groups. We investigate their Galois theoretic properties and discuss examples of Azumaya algebras arising from Galois descent.

On reconstructing finite gauge group from fusion rules

Journal of High Energy Physics
Gauging a finite group 0-form symmetry G of a quantum field theory (QFT) results in a QFT with a Rep(G) symmetry implemented by Wilson lines. The group G determines the fusion of Wilson lines.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Circulating Musclin is associated with skeletal muscle function and subclinical cardiac dysfunction in patients with cancer

British Journal of Pharmacology, EarlyView.
Background and Purpose Musclin (osteocrin) is a skeletal muscle‐derived peptide that has been implicated in cardioprotective signalling pathways. Its relevance in cancer patients, who frequently experience muscle wasting and cardiotoxicity, remains unclear. This study aimed to determine whether circulating Musclin levels reflect functional capacity and

Orthogonal bases of Brauer symmetry classes of tensors for groups having cyclic support on non-linear Brauer characters [PDF]

, 2016
This paper provides some properties of Brauer symmetry classes of tensors. A dimension formula is derived for the orbital subspaces in the Brauer symmetry classes of tensors corresponding to the irreducible Brauer characters of the groups whose non ...

Comparison of arithmetic Brauer groups with geometric Brauer groups

, 2020
Let $X$ be a projective and smooth variety over a field $k$. The goal of this paper is to prove that the cokernel of the canonical map $Br(X)\to Br(X_{k^s})^{G_k}$ has a finite exponent. Both groups are natural invariants arising from consideration of the Tate conjecture of divisors over $X$.
