F‐purity of binomial edge ideals
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract In 2012, Matsuda introduced the class of weakly closed graphs and investigated when binomial edge ideals are F‐pure. He proved that weakly closed binomial edge ideals are F‐pure whenever the base field has positive characteristic. He conjectured that: (i) when the base field has characteristic 2, every F‐pure binomial edge ideal comes from a ...

THE STRUCTURE OF BALANCED BIG COHEN–MACAULAY MODULES OVER COHEN–MACAULAY RINGS [PDF]
Glasgow Mathematical Journal, 2016 AbstractOver a Cohen–Macaulay (CM) local ring, we characterize those modules that can be obtained as a direct limit of finitely generated maximal CM modules. We point out two consequences of this characterization: (1) Every balanced big CM module, in the sense of Hochster, can be written as a direct limit of small CM modules.

Legal Brokers of Chinese Investment in Cambodia: Compliance Between Contract and Culture
Regulation &Governance, Volume 20, Issue 1, Page 162-175, January 2026.ABSTRACT In conventional understandings of compliance, lawyers and compliance officers internalize compliance within corporations. Complicating this model, this article argues that compliance professionals may occupy a Janus‐faced role between informality and formality.

Splitting the difference: Computations of the Reynolds operator in classical invariant theory
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract If G$G$ is a linearly reductive group acting rationally on a polynomial ring S$S$, then the inclusion SG↪S$S^{G} \hookrightarrow S$ possesses a unique G$G$‐equivariant splitting, called the Reynolds operator. We describe algorithms for computing the Reynolds operator for the classical actions as in Weyl's book.

Cohen-Macaulay modules over simple singularities
, 2022 The thesis is focused on the maximal Cohen-Macaulay modules over simple singular- ities. Previous results on the topic are summarised, and in particular it is shown that a hypersurface is MCM-finite if and only if it is a simple singularity.

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system
Limnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...

Gorenstein Injective Dimension and Cohen-Macaulayness
پژوهشهای ریاضی, 2019 Throughout this paper, (R, m) is a commutative Noetherian local ring with the maximal ideal m. The following conjecture proposed by Bass [1], has been proved by Peskin and Szpiro [2] for almost all rings: (B) If R admits a finitely generated R ...

Cohen–Macaulay multigraded modules
Illinois Journal of Mathematics, 2008 Let S be a standard N-graded algebra over a local ring A, and let M be a finitely generated Z-graded module over S. We characterize the CohenMacaulayness of M in terms of the vanishing of certain sheaf cohomology modules. As a consequence, we apply our result to study the Cohen-Macaulayness of multiRees modules. Our work extends previous studies on the

Polarization and Gorenstein liaison
Journal of the London Mathematical Society, Volume 112, Issue 6, December 2025.Abstract A major open question in the theory of Gorenstein liaison is whether or not every arithmetically Cohen–Macaulay subscheme of Pn$\mathbb {P}^n$ can be G‐linked to a complete intersection. Migliore and Nagel showed that if such a scheme is generically Gorenstein (e.g., reduced), then, after re‐embedding so that it is viewed as a subscheme of Pn ...

The shift‐homological spectrum and parametrising kernels of rank functions
Journal of the London Mathematical Society, Volume 112, Issue 6, December 2025.Abstract For any compactly generated triangulated category, we introduce two topological spaces, the shift spectrum and the shift‐homological spectrum. We use them to parametrise a family of thick subcategories of the compact objects, which we call radical.
