Dualities in convex algebraic geometry [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 2010 Convex algebraic geometry concerns the interplay between optimization theory and real algebraic geometry. Its objects of study include convex semialgebraic sets that arise in semidefinite programming and from sums of squares. This article compares three

Fundamental groups of symplectic singularities [PDF]
, 2013 Let (X, \omega) be an affine symplectic variety. Assume that X has a C^*-action with positive weights and \omega is homogeneous with respect to the C^*-action. We prove that the algebraic fundamental group of the smooth locus X_{reg} is finite. This is a

Multiresponsive Color‐Tunable Phosphorescence With Matrix‐Confined Clusters
Aggregate, EarlyView.The molecule with cluster‐triggered emission mechanisms is embedded in polymer matrix, the phosphorescence properties of multiclusters are size‐dependent and exhibit different responses to various stimuli, including temperature, concentration, and excitation, which synergistically induce color‐range tunable time‐dependent phosphorescence color behavior.

Groupes de Brauer algébriques modulo les constantes d’espaces homogènes et leurs compactifications
Comptes Rendus. MathématiqueLet $X$ be a smooth, geometrically integral variety without non-constant invertible functions over a field $K$. Then the quotient of the “algebraic” Brauer group of $X$ by $\mathrm{Br}\,K$ injects into $\mathrm{H}^1(K,\mathrm{Pic}{\overline{X}})$.

Action Type Geometrical Equivalence of Representations of Groups [PDF]
, 2005 For every variety of algebras and every algebras in these variety we can consider an algebraic geometry. Algebras may be many sorted (not necessarily one sorted) algebras. A set of sorts is fixed for each variety.

AIChE Journal, EarlyView.Abstract The modernization of pharmaceutical manufacturing is driving a shift from traditional batch processing to continuous alternatives. Synthesizing end‐to‐end optimal (E2EO) manufacturing routes is crucial for the pharmaceutical industry, especially when considering multiple operating modes—such as batch, continuous, or hybrid (containing both ...

Support Varieties for Selfinjective Algebras [PDF]
K-Theory, 2004 Support varieties for any finite dimensional algebra over a field were introduced by Snashall-Solberg using graded subalgebras of the Hochschild cohomology. We mainly study these varieties for selfinjective algebras under appropriate finite generation hypotheses.

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR
Advanced Intelligent Discovery, EarlyView.Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Advanced Intelligent Discovery, EarlyView.A crystal graph neural network based on the attention mechanism is proposed in this work. The model dynamically weights features through the attention mechanism, enabling precise prediction of properties of material from structural features. Here, taking Janus III–VI van der Waals heterostructures as a representative case, the properties have been ...
