Aggregation and the Structure of Value
Noûs, EarlyView.ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

On Multilevel Energy‐Based Fragmentation Methods
International Journal of Quantum Chemistry, Volume 126, Issue 3, January 30, 2026.We investigate the working equations of energy‐based fragmentation methods and present ML‐SUPANOVA, a Möbius‐inversion‐based multilevel fragmentation scheme that enables adaptive, quasi‐optimal truncations to efficiently approximate Born‐Oppenheimer potentials across hierarchies of electronic‐structure methods and basis sets.

Time‐ and Behaviour‐Preserving Execution of Determinate Supervisory Control
IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.The activity framework is a model‐based framework incorporating a model of activities with determinate timing and behaviour, and a strong mathematical foundation based on max‐plus algebra that allows efficient timing analysis and optimisation of CPS. Preserving the specified behaviour and the model‐predicted timing in an implementation is challenging ...

Knowledge Gradient Procedure to Select the Best System Under Pairwise Comparisons
Naval Research Logistics (NRL), Volume 72, Issue 8, Page 1078-1096, December 2025.ABSTRACT This article considers fixed‐budget ranking and selection (R&S) problems where the performance of alternative designs can only be assessed through pairwise comparisons, a setting encountered in many applications, including player ranking in games, sports tournaments, recommender systems, image‐based search, public choice models such as voting ...

Relational Bundle Geometric Formulation of Non‐Relativistic Quantum Mechanics
Fortschritte der Physik, Volume 73, Issue 12, December 2025.Abstract A bundle geometric formulation of non‐relativistic many‐particles Quantum Mechanics is presented. A wave function is seen to be a C$\mathbb {C}$‐valued cocyclic tensorial 0‐form on configuration space‐time seen as a principal bundle, while the Schrödinger equation flows from its covariant derivative, with the action functional supplying a ...

Random Structures &Algorithms, Volume 67, Issue 4, December 2025.ABSTRACT A finite group G$$ G $$ is mixable if a product of random elements, each chosen independently from two options, can distribute uniformly on G$$ G $$. We present conditions and obstructions to mixability. We show that 2‐groups, the symmetric groups, the simple alternating groups, several matrix and sporadic simple groups, and most finite ...

The flat cover conjecture for monoid acts
Journal of the London Mathematical Society, Volume 112, Issue 6, December 2025.Abstract We prove that the Flat Cover Conjecture holds for the category of (right) acts over any right‐reversible monoid S$S$, provided that the flat S$S$‐acts are closed under stable Rees extensions. The argument shows that the class F$\mathcal {F}$‐Mono (S$S$‐act monomorphisms with flat Rees quotient) is cofibrantly generated in such categories ...

On the section conjecture over fields of finite type
Mathematische Nachrichten, Volume 298, Issue 11, Page 3476-3493, November 2025.Abstract Assume that the section conjecture holds over number fields. We prove then that it holds for a broad class of curves defined over finitely generated extensions of Q$\mathbb {Q}$. This class contains every projective, hyperelliptic curve, every hyperbolic, affine curve of genus ≤2$\le 2$, and a basis of open subsets of any curve.

Scanner Data and the Construction of Inter‐Regional Price Indexes
Review of Income and Wealth, Volume 71, Issue 4, November 2025.ABSTRACT The paper uses scanner data to measure the welfare effects of differing product availability across six Japanese regions. To eliminate the chain drift problem associated with the use of scanner data, various multilateral indexes were computed: GEKS, Geary–Khamis, and Weighted Time Product Dummy Hedonic price indexes.

Centrality of star and monotone factorisations
Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3567-3585, November 2025.Abstract A factorisation problem in the symmetric group is central if conjugate permutations always have the same number of factorisations. We give the first fully combinatorial proof of the centrality of transitive star factorisations that is valid in all genera, which answers a natural question of Goulden and Jackson from 2009.
