Representing matrices, M-ideals and tensor products of L1-predual spaces
Extracta Mathematicae, 2018 Motivated by Bratteli diagrams of Approximately Finite Dimensional (AF) C* - algebras, we consider diagrammatic representations of separable L1 -predual spaces and show that, in analogy to a result in AF C* -algebra theory, in such spaces, every M-ideal ...

Journal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.ABSTRACT Background Traditionally, combining individual and collaborative learning happens in a pre‐planned and synchronised manner where the whole class switches between activities at the same time. However, in an era where personalised learning is showing great promise, a more dynamic way of combining the two activities may lead to better learning ...

A note on the bicategory of Landau-Ginzburg models (ℒ𝒢K) [PDF]
Surveys in Mathematics and its ApplicationsThe bicategory of Landau-Ginzburg models denoted by ℒ𝒢K possesses adjoints and this helps in explaining a certain duality that exists in the setting of Landau-Ginzburg models in terms of some specified relations. The construction of ℒ𝒢K is reminiscent of,

Models in Decision‐Making Under Risk and Uncertainty
Journal of Economic Surveys, Volume 40, Issue 1, Page 304-320, February 2026.ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...

Rigidity of anti‐de Sitter (2+1)‐spacetimes with convex boundary near the Fuchsian locus
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract We prove that globally hyperbolic compact anti‐de Sitter (2+1)‐spacetimes with a strictly convex spacelike boundary that is either smooth or polyhedral and whose holonomy is close to Fuchsian are determined by the induced metric on the boundary.

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.
