Noûs, EarlyView.ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

The Mathematical History Behind the Granger–Johansen Representation Theorem
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT When can a vector time series that is integrated once (i.e., becomes stationary after taking first differences) be described in error correction form? The answer to this is provided by the Granger–Johansen representation theorem. From a mathematical point of view, the theorem can be viewed as essentially a statement concerning the geometry of ...

Public Administration, EarlyView.ABSTRACT Artificial intelligence (AI) systems are increasingly being integrated into public sector decision‐making processes, with public managers relying on them to enhance their capabilities. As AI adoption becomes more widespread, discussions about its advantages and drawbacks intensify, alongside growing external expectations and pressures. However,

Relationships Between Shared Group Properties: Theory, Measurement, Estimation, and Adjustment
Personnel Psychology, EarlyView.ABSTRACT Teams researchers, meta‐analysts, and others often study relationships between group‐level constructs measured by aggregating individual‐level variables, but it is well‐known that group‐mean correlations are influenced by individual‐level relationships.

Personnel Psychology, EarlyView.ABSTRACT Strategic human resource management (HRM) scholars have extensively examined the impact of a high‐performance work system (HPWS) on firm performance outcomes and the conditions that influence this relationship. However, the factors that affect how intensively a firm uses an HPWS remain less understood.

(Co‐)Reference All the Way Down: A Unified Theory of (Pro) Nominals in Ordinary English
Theoria, EarlyView.ABSTRACT This essay joins two themes, both arising from Kripke's inspiring ideas in the theory of reference. The first theme concerns reference in general. The second examines the notion of co‐reference and the role it plays in a unified theory of pronouns for natural language.

On computing local monodromy and the numerical local irreducible decomposition
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Isomorphisms in switching classes of graphs [PDF]
, 1977 We introduce notation and terminology to investigate conditions on a permutation group G sufficient to ensure that G fixes a graph in any switching class of graphs that it stabilises. We show that cyclic groups, groups of odd order groups of order ^k+2 and all stabilisers of switching classes of graphs on an odd number of vertices have this property ...

Topological Graph Neural Networks: A Novel Approach for Geometric Deep Learning
Applied AI Letters, Volume 7, Issue 2, June 2026.This graphical abstract illustrates the Topological Graph Neural Network (TopGNN) architecture. It demonstrates a parallel processing approach where an input graph is simultaneously analyzed by a standard GNN Encoder to capture local node features and by Persistent Homology to extract global topological features (like cycles and voids), visualized as a
