On non-periodic groups whose finitely generated subgroups are either permutable or pronormal [PDF]
, 2013 summary:The current article considers some infinite groups whose finitely generated subgroups are either permutable or pronormal. A group $G$ is called a generalized radical, if $G$ has an ascending series whose factors are locally nilpotent or locally ...

SU(3) higher roots and their lattices [PDF]
, 2022 International audienceAfter recalling the notion of higher roots (or hyper-roots) associated with "quantum modules" of type (G, k), for G a semi-simple Lie group and k a positive integer, following the definition given by A. Ocneanu in 2000, we study the

When ${\rm Min}(G)^{-1}$ has a clopen $\pi $-base [PDF]
, 2021 summary:It is our aim to contribute to the flourishing collection of knowledge centered on the space of minimal prime subgroups of a given lattice-ordered group. Specifically, we are interested in the inverse topology.

Normal subgroups in the subgroup lattices of finite $p$-groups [PDF]
, 2006 Given a finite $p$-group $G$ we construct inductively a chief series only by lattice theoretical means. This improves a result of R. Schmidt that shows that any projectivity between finite $p$ groups $G$ and $H$ sends a chief series of $G$ into a chief ...

On $\sigma $-permutably embedded subgroups of finite groups [PDF]
, 2019 summary:Let $\sigma =\{\sigma _i\colon i\in I\}$ be some partition of the set of all primes $\mathbb {P}$, $G$ be a finite group and $\sigma (G)=\{\sigma _i\colon \sigma _i\cap \pi (G)\neq \emptyset \}$.

О модулярности решетки бэровских σ-локальных формаций [PDF]
, 2023 Throughout this paper, all groups are finite. A group class closed under taking homomorphic images and finite subdirect products is called a formation. The symbol σ denotes some partition of the set of all primes. V. G. Safonov, I. N. Safonova, A.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides
Advanced Functional Materials, EarlyView.We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Advanced Science, EarlyView.By overcoming the fixed‐path limitations of conventional machine learning, a heterogeneous graph neural network fundamentally reconstructs material data representation. Integrating variable processing sequences with intrinsic elemental features, this framework enables exploratory optimization across high‐dimensional spaces.
