Representation of 𝐴-convex algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
Algebraic properties of A A -convex algebras are developed via a functor to locally m m -convex algebras. The Gel’fand-Mazur theorem holds for A A -convex algebras, and this fact allows a Gel’fand-type representation theorem for a subclass of uniformly A A -convex algebras. Connections

The standard form of a representation-finite algebra

open access: yes, 1983
. - The importance of covering techniques for the investigation of the representations of finite-dimensional algebras is well-known since [RI 1] and [BG]. When the algebra A admits only finitely many isomorphism classes of indecomposable representations,

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

open access: yesAdvanced 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 4-CB algebra and solvable lattice models

open access: yesJournal of High Energy Physics, 2019
We study the algebras underlying solvable lattice models of the type fusion interaction round the face (IRF). We propose that the algebras are universal, depending only on the number of blocks, which is the degree of polynomial equation obeyed by the ...

Representation Theory of the Witt Algebra

open access: yes, 1998
1.1. Let g be a finite-dimensional restricted Lie algebra over an algebraically closed field of characteristic p ) 0. Every simple g-module is U Ĺ˝ w finite-dimensional and therefore admits a character x g g see SF, x. U Theorem 5.2.5 .

A Shared Control Method of Multiobjective Motion Fusion for Surgical Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper proposes an innovative shared control method that can handle multiple objectives task by integrating various types of controllers. It not only takes into account the priorities among the objectives but also allows for the flexible addition or removal of objective controllers.

Reprogrammable, In‐Materia Matrix‐Vector Multiplication with Floppy Modes

open access: yesAdvanced Intelligent Systems, EarlyView.
This article describes a metamaterial that mechanically computes matrix‐vector multiplications, one of the fundamental operations in artificial intelligence models. The matrix multiplication is encoded in floppy modes, near‐zero force deformations of soft matter systems.

Bundles of Banach algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
We study bundles of Banach algebras π:A→X, where each fiber Ax=π−1({x}) is a Banach algebra and X is a compact Hausdorff space. In the case where all fibers are commutative, we investigate how the Gelfand representation of the section space algebra Γ(π ...
