Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Chromatic quasisymmetric functions and noncommutative 𝑃-symmetric functions
Transactions of the American Mathematical SocietyFor a natural unit interval order P P , we describe proper colorings of the incomparability graph of P P in the language of heaps. We also introduce a combinatorial operation, called a local flip, on the heaps. This operation defines an equivalence relation on the proper colorings, and the equivalence relation refines

Hopf algebras of endomorphisms of Hopf algebras
, 2004 In the last decennia two generalizations of the Hopf algebra of symmetric functions have appeared and shown themselves important, the Hopf algebra of noncommutative symmetric functions NSymm and the Hopf algebra of quasisymmetric functions QSymm.

A Bijection between Atomic Partitions and Unsplitable Partitions
, 2010 In the study of the algebra $\mathrm{NCSym}$ of symmetric functions in noncommutative variables, Bergeron and Zabrocki found a free generating set consisting of power sum symmetric functions indexed by atomic partitions.

A Combinatorial Perspective on the Noncommutative Symmetric Functions
The Electronic Journal of CombinatoricsThe noncommutative symmetric functions $\textbf{NSym}$ were first defined abstractly by Gelfand et al. in 1995 as the free associative algebra generated by noncommuting indeterminates $\{\boldsymbol{e}_n\}_{n\in \mathbb{N}}$ that were taken as a noncommutative analogue of the elementary symmetric functions.

Noncommutative symmetric functions and quasi-symmetric functions with two and more paramters
, 2001 We define two-parameter families of noncommutative symmetric functions and quasi-symmetric functions, which appear to be the proper analogues of the Macdonald symmetric functions in these settings.

Symmetric functions in noncommuting variables in superspace
Discrete MathematicsIn 2004, Rosas and Sagan developed the theory of symmetric functions in noncommuting variables, achieving results analogous to classical symmetric functions. On the other hand, in 2004, Desrosiers, Lapointe and Mathieu introduced the theory of symmetric functions in superspace, which involve both commuting and anticommuting variables, extending the ...
