Mixing quantum and classical mechanics and uniqueness of Planck's constant [PDF]

, 2003
Observables of quantum or classical mechanics form algebras called quantum or classical Hamilton algebras respectively (Grgin E and Petersen A (1974) {\it J Math Phys} {\bf 15} 764\cite{grginpetersen}, Sahoo D (1977) {\it Pramana} {\bf 8} 545\cite{sahoo})

Tensor products of classifiable C∗-algebras [PDF]

Journal of Topology and Analysis, 2016
Let [Formula: see text] be the class of all unital separable simple [Formula: see text]-algebras [Formula: see text] such that [Formula: see text] has tracial rank no more than one for all UHF-algebra [Formula: see text] of infinite type. It has been shown that all amenable [Formula: see text]-stable [Formula: see text]-algebras in [Formula: see text ...

Soft‐Layered Composites with Wrinkling‐Activated Multi‐Linear Elastic Behavior, Stress Mitigation, and Enhanced Strain Energy Storage

Advanced Engineering Materials, EarlyView.
In this study, exciting new bi‐/multi‐linear elastic behavior of soft elastic composites that accompany the activation of wrinkling in the embedded interfacial layers is analyzed. The new features and performance of these composite materials, including dramatic enhancements in energy storage, can be tailored by the concentration of interfacial layers ...

Invariant and coinvariant spaces for the algebra of symmetric polynomials in non-commuting variables [PDF]

Discrete Mathematics & Theoretical Computer Science, 2008
We analyze the structure of the algebra $\mathbb{K}\langle \mathbf{x}\rangle^{\mathfrak{S}_n}$ of symmetric polynomials in non-commuting variables in so far as it relates to $\mathbb{K}[\mathbf{x}]^{\mathfrak{S}_n}$, its commutative counterpart.

Azumaya Monads and Comonads

Axioms, 2015
The definition of Azumaya algebras over commutative rings \(R\) requires the tensor product of modules over \(R\) and the twist map for the tensor product of any two \(R\)-modules.

Operator space projective tensor product of $C^*$-algebras [PDF]

Journal of the Australian Mathematical Society, 2001
. For a finite dimensional $ C^*$-algebra A and any $ C^*$-algebra B, we determine a constant of equivalence of operator space projective norm $ \| \cdot \|_\wedge$ and the Banach space projective norm $ \| \cdot \|_\gamma $ on $ A \otimes B $.

Graph Attention Neural Networks for Interpretable and Generalizable Prediction of Janus III–Vi Van Der Waals Heterostructures

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 ...

The space of ideals in the minimal tensor product of C*-algebras [PDF]

Mathematical Proceedings of the Cambridge Philosophical Society, 2009
For C*-algebras A1, A2 the map (I1, I2) → ker(qI1 ⊗ qI2) from Id′(A1) × Id′(A2) into Id′(A1 ⊗minA2) is a homeomorphism onto its image which is dense in the range.
