Bootstrapping non-commutative gauge theories from L∞ algebras
Journal of High Energy Physics, 2018 Non-commutative gauge theories with a non-constant NC-parameter are investigated. As a novel approach, we propose that such theories should admit an underlying L∞ algebra, that governs not only the action of the symmetries but also the dynamics of the ...

Non-commutative geometry, multiscalars, and the symbol map [PDF]
Nuclear Physics B - Proceedings Supplements, 1996 Starting from the concept of the universal exterior algebra in non-commutative differential geometry we construct differential forms on the quantum phase-space of an arbitrary system. They bear the same natural relationship to quantum dynamics which ordinary tensor fields have with respect to classical hamiltonian dynamics.

Automorphism groups of P1$\mathbb {P}^1$‐bundles over geometrically ruled surfaces
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract We classify the pairs (X,π)$(X,\pi)$, where π:X→S$\pi \colon X\rightarrow S$ is a P1$\mathbb {P}^1$‐bundle over a non‐rational geometrically ruled surface S$S$ and Aut∘(X)$\mathrm{Aut}^\circ (X)$ is relatively maximal, that is, maximal with respect to the inclusion in the group Bir(X/S)$\mathrm{Bir}(X/S)$.

Modular forms in the spectral action of Bianchi IX gravitational instantons
Journal of High Energy Physics, 2019 We prove a modularity property for the heat kernel and the Seeley-deWitt coefficients of the heat kernel expansion for the Dirac-Laplacian on the Bianchi IX gravitational instantons.

On the canonical bundle formula in positive characteristic
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Let f:X→Z$f:X\to Z$ be a fibration from a normal projective variety X$X$ of dimension n$n$ onto a normal curve Z$Z$ over a perfect field of characteristic p>2$p>2$. Let (X,B)$(X,B)$ be a dlt pair such that the induced pair on a general fibre is log canonical.

Non-commutative Projective Geometry as a Tool
, 2000 Today, non-commutative projective geometry is an independent area of research, yet it grew from a need to find new tools for understanding algebras arising in quantum physics.

Subregular representations of Sln and simple singularities of type An-1. Part II [PDF]
, 2003 The aim of this paper is to show that the structures on K-theory used to formulate Lusztig's conjecture for subregular nilpotent sln-representations are, in fact, natural in the McKay correspondence.

Simulating general relativity and non-commutative geometry by non-paraxial quantum fluids
New Journal of Physics, 2019 We show that quantum fluids enable experimental analogs of relativistic orbital precession in the presence of non-paraxial effects. The analysis is performed by the hydrodynamic limit of the Schrödinger equation.

Independence and strong independence complexes of finite groups
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Let G$G$ be a finite group. In [10], two different concepts of independence (namely, independence and strong independence) are introduced for the subsets of G$G$, yielding to the definition of two simplicial complexes whose vertices are the elements of G$G$. The strong independence complex Σ∼(G)$\tilde{\Sigma }(G)$ turns out to be a subcomplex

Commutative and non-commutative parallelogram geometry: en experimental approach
, 2013 28 p., figures produced by using geogebraBy ''parallelogram geometry'' we mean the elementary, ''commutative'', geometry corresponding to vector addition, and by ''trapezoid geometry'' a certain ''non-commutative deformation'' of the former.
