On 𝒜-submodules for reflexive operator algebras [PDF]
Proceedings of the American Mathematical Society, 1988 In [2] the authors described all weakly closed A \mathcal {A} -submodules of L ( H ) L\left ( H \right ) for a nest algebra A \mathcal {A} in terms of order homomorphisms of Lat A \mathcal {A} .

Reflexivity of operator algebras of finite split strict multiplicity [PDF]
Operators and Matrices, 2011 We study the invariant subspaces of abelian operator algebras of finite split strict multiplicity. We give sufficient conditions for the reflexivity and hereditary reflexivity of these algebras.

Coulomb branch algebras via symplectic cohomology
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract Let (M¯,ω)$(\bar{M}, \omega)$ be a compact symplectic manifold with convex boundary and c1(TM¯)=0$c_1(T\bar{M})=0$. Suppose that (M¯,ω)$(\bar{M}, \omega)$ is equipped with a convex Hamiltonian G$G$‐action for some connected, compact Lie group G$G$.

Opening the Black Box of EU Digital Sovereignty: A Macro‐Level Analysis of the Concept's Development
Governance, Volume 39, Issue 2, April 2026.ABSTRACT Digital sovereignty has emerged as a central organizing principle in European Union governance, yet systematic understanding of its conceptual evolution remains limited. This article provides the first macro‐level analysis of how digital sovereignty evolves across institutional and academic domains.

On the ranks of single elements of reflexive operator algebras [PDF]
Proceedings of the American Mathematical Society, 1997 Summary: For any completely distributive subspace lattice \(\mathfrak{L}\) on a real or complex reflexive Banach space and a positive integer \(n\), necessary and sufficient (lattice-theoretic) conditions are given for the existence of a single element of \(\text{Alg}\mathfrak{L}\) of rank \(n\). Similar conditions are given for the existence of single

A Miyaoka–Yau inequality for hyperplane arrangements in CPn$\mathbb {CP}^n$
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract Let H$\mathcal {H}$ be a hyperplane arrangement in CPn$\mathbb {CP}^n$. We define a quadratic form Q$Q$ on RH$\mathbb {R}^{\mathcal {H}}$ that is entirely determined by the intersection poset of H$\mathcal {H}$. Using the Bogomolov–Gieseker inequality for parabolic bundles, we show that if a∈RH$\mathbf {a}\in \mathbb {R}^{\mathcal {H}}$ is ...

Ewald's Conjecture and integer points in algebraic and symplectic toric geometry
Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.Abstract We solve several open problems concerning integer points of reflexive smooth polytopes, also known as monotone polytopes. While the paper belongs to the realm of discrete geometry, the connection with symplectic and algebraic geometry appears naturally since these polytopes have an important role in both areas.

Banach representations and affine compactifications of dynamical systems
, 2013 To every Banach space V we associate a compact right topological affine semigroup E(V). We show that a separable Banach space V is Asplund if and only if E(V) is metrizable, and it is Rosenthal (i.e.
