The meso-structures analysis of truss-like lightweight materials based on symmetric groups

open access: yesMaterials Research Express, 2023
Truss-like lightweight materials (TLLMs) with superior mechanical performance and excellent energy absorption capability are extensively used in aerospace and automobile industries.

Admissible groups, symmetric factor sets, and simple algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Let K be a field of characteristic zero and suppose that D is a K-division algebra; i.e. a finite dimensional division algebra over K with center K. In Mollin [1] we proved that if K contains no non-trivial odd order roots of unity, then every finite odd

On the Modular Representations of the Symmetric Group (III) [PDF]

open access: yesProceedings of the National Academy of Sciences, 1951
1. Introduction. It has been observed (2) that the number of p-regular classes of Sn, i.e. the number of classes of order prime to p, is equal to the number of partitions (λ) of n in which no summand is repeated p or more times. For this relation to hold it is essential that p be prime. It seems natural to call the Young diagram [λ] associated with (λ)

Empirical validation of the use of projective techniques in psychological testing using Galois fields

open access: yesFrontiers in Applied Mathematics and Statistics
It is shown that the problem of the adequacy of psychological testing methods, which are varieties of “projective techniques”, is far from being universally recognized.

The symmetric genus of alternating and symmetric groups

open access: yesJournal of Combinatorial Theory, Series B, 1985
The symmetric genus of a finite group G has been defined by Thomas W. Tucker as the smallest genus of all surfaces on which G acts faithfully as a group of automorphisms (some of which may reverse the orientation of the surface). This note announces the symmetric genus of all finite alternating and symmetric groups.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Characters of symmetric groups in terms of free cumulants and Frobenius coordinates [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
Free cumulants are nice and useful functionals of the shape of a Young diagram, in particular they give the asymptotics of normalized characters of symmetric groups $\mathfrak{S}(n)$ in the limit $n \to \infty$.
