Quantising chiral bosons on Riemann surfaces

open access: yesJournal of High Energy Physics
Sen’s action in two dimensions governs a chiral boson coupled to a two-dimensional metric together with a second chiral boson that couples to a flat two-dimensional metric. This second scalar decouples from the physical degrees of freedom.

Proteomic and Transcriptomic Signatures of Poor Asthma Symptom Control in the U‐BIOPRED Cohort

open access: yesAllergy, EarlyView.
No stable features were identified as associated with asthma symptom control in transcriptomics or sputum proteomics. Higher TWEAKR/TNFRSF12A and MBL/MBP‐C serum levels increased the odds of uncontrolled symptoms, while higher MK08/MAPK8 and CD5L serum levels decreased the odds, after adjustment for clinical variables.

Topological Classification of Conformal Actions on pq-Hyperelliptic Riemann Surfaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
A compact Riemann surface X of genus g>1 is said to be p-hyperelliptic if X admits a conformal involution ρ, for which X/ρ is an orbifold of genus p. If in addition X is q-hyperelliptic, then we say that X is pq-hyperelliptic.

Real‐Time Conformal Maps and Parameterizations

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a simple algorithm to conformally map between two simple and bounded planar domains based on the concept of harmonic measure, which is a conformal invariant. With suitable preprocessing, the algorithm is fast enough to compute all possible conformal maps (having three real degrees of freedom) between the two domains in real time in

Optimal Selling Mechanisms With Endogenous Seller Outside Offers

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We examine a two‐stage selling mechanism design problem, where the buyer makes her report and the seller endogenously decides his effort (hidden investment) to generate a possibly better outside offer. The optimal mechanism shows that the seller's effort depends on the reported value of the buyer; a higher value lowers the seller's incentive ...

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 4, Page 1012-1072, April 2026.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

Dynamically encircling an exceptional point through phase-tracked closed-loop control

open access: yesCommunications Physics
The intricate complex eigenvalues of non-Hermitian Hamiltonians manifest as Riemann surfaces in control parameter spaces. At the exceptional points (EPs), the degeneracy of both eigenvalues and eigenvectors introduces noteworthy topological features ...

Anomaly inflow for M5-branes on punctured Riemann surfaces

open access: yesJournal of High Energy Physics, 2019
We derive the anomaly polynomials of 4d N = 2 $$ \mathcal{N}=2 $$ theories that are obtained by wrapping M5-branes on a Riemann surface with arbitrary regular punctures, using anomaly inflow in the corresponding M-theory setup.

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

The Enriquez connection for higher genus polylogarithms

open access: yesJournal of High Energy Physics
We study the variation of the Enriquez connection for higher genus polylogarithms under degenerations of Riemann surfaces with marked points, and show that this connection becomes the connection constructed by the author for degenerating families of ...
