The Geometry of Quantum Computing
https://arxiv.org/pdf/2312.14807
E. Ercolessi, R. Fioresi, T. Weber
In this expository paper we present a brief introduction to the ge-
ometrical modeling of some quantum computing problems. After a
brief introduction to establish the terminology, we focus on quantum
information geometry and ZX-calculus, establishing a connection be-
tween quantum computing questions and quantum groups, i.e. Hopf
algebras.

One loop effective actions in Kerr-(A)dS Black Holes
https://arxiv.org/abs/2405.13830
Paolo Arnaudo, Giulio Bonelli, Alessandro Tanzini
We compute new exact analytic expressions for one-loop scalar effective actions in Kerr (A)dS black hole (BH) backgrounds in four and five dimensions. These are computed by the connection coefficients of the Heun equation via a generalization of the Gelfand-Yaglom formalism to second-order linear ODEs with regular singularities. The expressions we find are in terms of Nekrasov-Shatashvili special functions, making explicit the analytic properties of the one-loop effective actions with respect to the gravitational parameters and the precise contributions of the quasi-normal modes. The latter arise via an associated integrable system. In particular, we prove asymptotic formulae for large angular momenta in terms of hypergeometric functions and give a precise mathematical meaning to Rindler-like region contributions. Moreover we identify the leading terms in the large distance expansion as the point particle approximation of the BH and their finite size corrections as encoding the BH tidal response. We also discuss exact properties of the thermal version of the BH effective actions. Although we focus on the real scalar field in dS-Kerr and (A)dS-Schwarzschild in four and five dimensions, similar formulae can be given for higher spin matter and radiation fields in more general gravitational backgrounds.

Quantum Chiral Superfields
We study the supersymmetric extension of the conformal symmetry and ordinary super spacetime over the complex field. The different types of superspaces can all be seen Grassmannians or flag supermanifolds (that is, sets of subspaces of a given space). We introduce non commutative coordinates in (super) spacetime in such a way that the symmetries are preserved. In order to do so, the symmetry (super) group become also non commutative space or 'quantum group'.

On Uniqueness of Submaximally Symmetric Vector Ordinary Differential Equations of C-Class
A well-known classical result due to Sophus Lie is the classification of scalar ODEs with maximal and submaximal symmetry. Proving analogous results for vector ODEs in fully generality is not feasible using Lie-theoretic techniques. Instead, Cartan geometric and representation-theoretic tools are used to completely resolve the problem for vector ODEs in the so-called C-class.

ON RELATIVE TRACTOR BUNDLES
https://arxiv.org/pdf/2405.13614
ANDREAS CAP, ZHANGWEN GUO, AND MICHAL WASILEWICZ
This article contributes to the relative BGG-machinery for para-
bolic geometries. Starting from a relative tractor bundle, this machinery con-
structs a sequence of differential operators that are naturally associated to the
geometry in question. In many situations of interest, it is known that this se-
quence provides a resolution of a sheaf that can locally be realized as a pullback
from a local leaf space of a foliation that is naturally available in this situation.
An explicit description of the latter sheaf was only available under much more
restrictive assumptions.

The fuzzy bit
In this paper we revise the idea of appliying fuzzy sets to quantum theory. It is established that, appropriately using a particular Universe of discourse, Quantum Mechanics can be expressed as a theory of fuzzy sets, according to a result by Pycakz for quantum logics in general.
