The log Grothendieck ring of varieties

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We define a Grothendieck ring of varieties for log schemes. It is generated by one additional class “P$P$” over the usual Grothendieck ring. We show the naïve definition of log Hodge numbers does not make sense for all log schemes. We offer an alternative that does.

Carrollian approach to 1 + 3D flat holography

open access: yesJournal of High Energy Physics, 2023
The isomorphism between the (extended) BMS4 algebra and the 1 + 2D Carrollian conformal algebra hints towards a co-dimension one formalism of flat holography with the field theory residing on the null-boundary of the asymptotically flat space-time ...

Residually rationally solvable one‐relator groups

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We show that the intersection of the rational derived series of a one‐relator group is rationally perfect and is normally generated by a single element. As a corollary, we characterise precisely when a one‐relator group is residually rationally solvable.

Pion transition form factor in the domain model of QCD vacuum

open access: yesEPJ Web of Conferences, 2017
Domain model of QCD allows for description of wide range of meson observables, dynamical chiral symmetry breaking, and resolution of UA(1) and strong CP problems.

Anomaly matching in the symmetry broken phase: Domain walls, CPT, and the Smith isomorphism

open access: yesSciPost Physics, 2020
Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes or a topological field theory. If the symmetry is spontaneously broken,

Addition Theorems for Finite Abelian Groups

open access: yesJournal of Number Theory, 1995
Sei \(G\) eine abelsche Gruppe der Ordnung \(n\) und \(S= (a_1, \dots, a_k)\) eine Folge von Elementen aus \(G\), wobei Wiederholungen erlaubt sind. Für \(r\) mit \(1\leq r< k\) wird definiert \(\sum_{\leq r} (S):= \{a_{i_1}+ \dots+ a_{i_l}\mid 1\leq i_1< \dots< i_l\leq k\); \(1\leq \ell\leq r\}\) und \(\sum_r (S):= \{a_{i_1}+ \dots+ a_{i_r}\mid 1\leq ...

Torsion classes of extended Dynkin quivers over commutative rings

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract For a Noetherian R$R$‐algebra Λ$\Lambda$, there is a canonical inclusion torsΛ→∏p∈SpecRtors(κ(p)Λ)$\mathop {\mathsf {tors}}\Lambda \rightarrow \prod _{\mathfrak {p}\in \operatorname{Spec}R}\mathop {\mathsf {tors}}(\kappa (\mathfrak {p})\Lambda)$, and each element in the image satisfies a certain compatibility condition.

Quantum hs-Yang-Mills from the IKKT matrix model

open access: yesNuclear Physics B
We study the one-loop effective action of the higher-spin gauge theory induced by the IKKT matrix model on a M1,3×K background, where M1,3 is an FLRW cosmological spacetime brane and K are compact fuzzy extra dimensions.

Radical preservation and the finitistic dimension

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We introduce the notion of radical preservation and prove that a radical‐preserving homomorphism of left artinian rings of finite projective dimension with superfluous kernel reflects the finiteness of the little finitistic, big finitistic, and global dimension.

Profinite direct sums with applications to profinite groups of type ΦR$\Phi _R$

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We show that the ‘profinite direct sum’ is a good notion of infinite direct sums for profinite modules, having properties similar to those of direct sums of abstract modules. For example, the profinite direct sum of projective modules is projective, and there is a Mackey's formula for profinite modules described using these sums.
