Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, EarlyView.
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 ...

Cosmology as a CFT1

Journal of High Energy Physics, 2019
We show that the simplest FLRW cosmological system consisting in the homo- geneous and isotropic massless Einstein-Scalar system enjoys a hidden conformal symmetry under the 1D conformal group SL(2, ℝ) acting as Mobius transformations in proper time ...

Statistical Lie algebras of a constant curvature and locally conformally Kähler Lie algebras

, 2021
We show that a statistical manifold manifold of a constant non-zero curvature can be realised as a level line of Hessian potential on a Hessian cone. We construct a Sasakian structure on $TM\times\R$ by a statistical manifold manifold of a constant non-zero curvature on $M$. By a statistical Lie algebra of a constant non-zero Lie algebra we construct a

Compactifications of strata of differentials

Bulletin of the London Mathematical Society, EarlyView.
Abstract In this informal expository note, we quickly introduce and survey compactifications of strata of holomorphic 1‐forms on Riemann surfaces, that is, spaces of translation surfaces. In the last decade, several of these have been constructed, studied, and successfully applied to problems.

Emergence of spacetime from the algebra of total modular Hamiltonians

Journal of High Energy Physics, 2019
We study the action of the CFT total modular Hamiltonian on the CFT representation of bulk fields with spin. In the vacuum of the CFT the total modular Hamiltonian acts as a bulk Lie derivative, reducing on the RT surface to a boost perpendicular to the ...

Homogeneous Multigrid for Hybrid Discretizations: Application to HHO Methods

Numerical Methods for Partial Differential Equations, Volume 41, Issue 5, September 2025.
ABSTRACT We prove the uniform convergence of the geometric multigrid V‐cycle for hybrid high‐order (HHO) and other discontinuous skeletal methods. Our results generalize previously established results for HDG methods, and our multigrid method uses standard smoothers and local solvers that are bounded, convergent, and consistent.

Topology in Biological Piezoelectric Materials

Advanced Materials, Volume 37, Issue 32, August 14, 2025.
This review summarizes the topological structures in biological piezoelectric materials, covering morphology evolution, spatial arrangement, and biomimetic strategies. These topologies modulate structure‐property relationships across multiple scales, enabling performance enhancement and multifunctional integration.

Fermionic CFTs from topological boundaries in abelian Chern-Simons theories

Journal of High Energy Physics
A quantum field theory is referred to as bosonic (non-spin) if its physical quantities are independent of the spacetime spin structure, and as fermionic (spin) if they depend on it.

A Flexible Approach to Quantile Regression Modeling With Unit Burr‐XII‐Poisson and Its Applications to Cancer, Chemotherapy, and Energy Data

Engineering Reports, Volume 7, Issue 8, August 2025.
ABSTRACT This article introduces the unit‐Burr XII‐Poisson (UBXIIP) distribution, a flexible model for bounded data in the unit interval. Unlike many existing alternatives, the UBXIIP offers enhanced versatility in modeling unit‐domain phenomena. We further develop a quantile‐based regression framework by reparameterizing the UBXIIP, enabling the ...

The non-Abelian tensor multiplet

Journal of High Energy Physics, 2018
We assume the existence of a background vector field that enables us to make an ansatz for the superconformal transformations for the non-Abelian 6d (1, 0) tensor multiplet.
