Darboux soft hair in 3D asymptotically flat spacetimes

Physics Letters B
In this paper, we construct a fully on-shell solution space for three-dimensional Einstein's gravity in asymptotically flat spacetimes using a finite coordinate transformation.

A Re‐Examination of Foundational Elements of Cosmology

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT This paper undertakes a conceptual re‐examination of several foundational elements of cosmology through the lens of spacetime symmetries. A new derivation of the Friedmann–Lemaître–Robertson–Walker metric is obtained by a careful conceptual examination of rotations and translations on generic manifolds, followed by solving the rotational and ...

The L$L$‐polynomials of van der Geer–van der Vlugt curves in characteristic 2

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract The van der Geer–van der Vlugt curves form a class of Artin–Schreier coverings of the projective line over finite fields. We provide an explicit formula for their L$L$‐polynomials in characteristic 2, expressed in terms of characters of maximal abelian subgroups of the associated Heisenberg groups.

The Straightening Identity in the Universal Enveloping Algebra of the Heisenberg Algebra

PUMP journal of undergraduate research
This work aims to formulate and prove the nontrivial straightening identity in the universal enveloping algebra of the Heisenberg algebra. This identity is a special case of the Baker-Campbell-Hausdorff formula, but was proven using a new proof method of

Linear Hamiltonian Vector Fields on Lie Groups

Mathematics
Linear vector fields on Lie groups constitute a fundamental class of dynamical systems, as their flows are one-parameter subgroups of automorphisms and their infinitesimal behavior is entirely determined by derivations of the Lie algebra.

Matrix Bosonic realizations of a Lie colour algebra with three generators and five relations of Heisenberg Lie type

, 2009
We describe realizations of a Lie colour algebra with three generators and ve relations by matrices of power series in noncommuting indeterminates satisfying Heisenberg's canonical commutation relation of quantum mechanics. The obtained formulas are used

Spread complexity for the planar limit of holography

Journal of High Energy Physics
Complexity is a fundamental characteristic of states within a quantum system. Its use is however mostly limited to bosonic systems, inhibiting its present applicability to supersymmetric theories.

Θ-Superderivations in Lie Superalgebras: Structural Properties and Decomposition Theorems

Mathematics
This work presents a graded investigation of Θ-superderivations within the framework of Lie superalgebras, generalizing the Θ-derivation concept from ordinary Lie algebras to graded settings.
