On regular subgroup functors of finite groups

Open Mathematics, 2022
A subgroup functor τ\tau is said Φ\Phi -regular if for all primitive groups GG, whenever H∈τ(G)H\in \tau \left(G) is a pp-subgroup and NN is a minimal normal subgroup of GG, then ∣G:NG(H∩N)∣=pd| G:{N}_{G}\left(H\cap N)| ={p}^{d} for some integer dd.

Factorizations of Primitive Permutation Groups

Journal of Algebra, 1997
The author gives a complete classification of those finite primitive permutation groups which admit a factorization as a product of a point stabilizer and an automorphic image of it: \(G=G_\omega G^\alpha_\omega\). Using the types given in the O'Nan-Scott theorem the following cases are obtained: (i) If \(G\) is affine then \(G=(E_{2^3}L_3(2))\text{ wr

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

Advanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

The Unipotency of Eleventh Order Matrix Group with no More than Seven Jordan Blocks

Journal of Harbin University of Science and Technology
By avoiding complex research methods involving Lie algebra and Lie superalgebra, and instead utilizing simple theories such as matrix logarithm and expansion of product of non commutative polynomial, the new combination property of primitive elements of ...

Delegating a Product of Group Exponentiations with Application to Signature Schemes (Submission to Special NutMiC 2019 Issue of JMC)

Journal of Mathematical Cryptology, 2020
Many public-key cryptosystems and, more generally, cryptographic protocols, use group exponentiations as important primitive operations. To expand the applicability of these solutions to computationally weaker devices, it has been advocated that a ...

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

Advanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

The Unipotency of Linear Groups Generated by Matrices with Primitive  Elements Contain no more than Six Jorden Blocks

Journal of Harbin University of Science and Technology, 2019
In order to solve the problem of whether the matrices generated by two unipotent matrices are unipotency, a new combinatorial property of generators of free groups is obtained by using the matrix logarithmic tool。From the point of the combination of ...

Successive Orthorhombic Distortions in Kagome Metals by Molecular Orbital Formation

Advanced Materials, EarlyView.
Orthorhombic distortions in kagome metals break the symmetry required for exotic charge order. Synchrotron X‐ray diffraction of NdRu3Si2 reveals successive orthorhombic transitions driven by molecular orbital formation between kagome layers. The frustrated kagome lattice hosts degenerate patterns of kagome dimers whose short‐range correlations produce ...

Vertical Self‐Rectifying Memristive Arrays for Page‐Wise Parallel Logic and Arithmetic Processing

Advanced Materials, EarlyView.
This study proposes a page‐wise logic‐in‐memory architecture realized in a 3D vertical resistvie random‐access memory array of self‐rectifying memristors. By introducing intra‐ and inter‐page logic primitives, the system enables Boolean and arithmetic operations to be executed directly within the memory.
