Symmetric Polynomials in Free Associative Algebras—II

open access: yesMathematics, 2023
Let K⟨Xd⟩ be the free associative algebra of rank d≥2 over a field, K. In 1936, Wolf proved that the algebra of symmetric polynomials K⟨Xd⟩Sym(d) is infinitely generated.

Scalar Field Cosmology from a Modified Poisson Algebra

open access: yesMathematics, 2022
We investigate the phase space of a scalar field theory obtained by minisuperspace deformation. We consider quintessence or phantom scalar fields in the action that arises from minisuperspace deformation on the Einstein–Hilbert action.

HiTIM: Hierarchical Task Information Mining for Few-Shot Action Recognition

open access: yesApplied Sciences, 2023
Although the existing few-shot action recognition methods have achieved impressive results, they suffer from two major shortcomings. (a) During feature extraction, few-shot tasks are not distinguished and task-irrelevant features are obtained, resulting ...

Hydrogen-, Helium-, and Lithium-like Bound States in Classical and Quantum Plasmas

open access: yesPlasma, 2022
We study the effective interactions and the mass action constants for pair and triple associations in classical and quantum plasmas. Avoiding double counting, we derive new expressions for the mass action constants.

Semantic Activation in Badminton Action Processing and Its Modulation by Action Duration: An ERP Study

open access: yesBrain Sciences, 2022
Action processing is crucial for sports activities. Using event-related potentials (ERPs), the present study investigated whether semantics were activated in action processing and, if so, whether semantic activation was modulated by action duration ...
