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 ...

Quasinormal Modes for Coherent Quantum Black Holes
Fortschritte der Physik, Volume 74, Issue 3, March 2026.ABSTRACT Coherent quantum black holes are quantum geometries obtained by means of a mean‐field‐like approach to the gravitational interaction. This procedure attenuates the classical spacetime singularities of general relativity by replacing them with integrable singularities in the quantum‐corrected geometry. After discussing some relevant observables

Braided Hopf algebras, double constructions, and applications [PDF]
, 2015 This thesis contains four related papers which study different aspects of double constructions for braided Hopf algebras. The main result is a categorical action of a braided version of the Drinfeld center on a Heisenberg analogue, called the Hopf center.

Physics Letters B, 2016 Dans cet article, nous proposerons la forme la plus générale de la déformation de l'algèbre de Heisenberg motivée par le principe d'incertitude généralisée. Cette déformation de l'algèbre de Heisenberg va déformer tous les systèmes de mécanique quantique.

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.

On boson algebras as Hopf algebras [PDF]
, 1997 Certain types of generalized undeformed and deformed boson algebras which admit a Hopf algebra structure are introduced, together with their Fock-type representations and their corresponding R-matrices.

Equivariant K -Theory, Generalized Symmetric Products, and Twisted Heisenberg Algebra [PDF]
Communications in Mathematical Physics, 2003 For a space X acted by a finite group $\G$, the product space $X^n$ affords a natural action of the wreath product $\Gn$. In this paper we study the K-groups $K_{\tG_n}(X^n)$ of $\Gn$-equivariant Clifford supermodules on $X^n$. We show that $\tFG =\bigoplus_{n\ge 0}K_{\tG_n}(X^n) \otimes \C$ is a Hopf algebra and it is isomorphic to the Fock space of a

New special Einstein pseudo-Riemannian metrics on solvable Lie algebras [PDF]
, 2022 We exhibit a concrete procedure to construct Einstein pseudo-Kähler and para-Kähler metrics on solvable Lie algebras. We apply this method to classify all the rank-one pseudo-Iwasawa extensions of type-(Nil4) nilsoliton in low dimension.

Quantized Nambu-Poisson manifolds and n-Lie algebras [PDF]
, 2010 We investigate the geometric interpretation of quantized Nambu-Poisson structures in terms of noncommutative geometries. We describe an extension of the usual axioms of quantization in which classical Nambu-Poisson structures are translated to n-Lie ...
