Character Theory of Symmetric Groups and Subgroup Growth of Surface Groups [PDF]

Journal of the London Mathematical Society, 2002
Summary: Results from the character theory of symmetric groups are used to obtain an asymptotic estimate for the subgroup growth of fundamental groups of closed 2-manifolds. The main result implies an affirmative answer, for the class of groups investigated, to a question of Lubotzky's concerning the relationship between the subgroup growth of a one ...

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

Advanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Local connections of layer 5 GABAergic interneurons to corticospinal neurons

Frontiers in Neural Circuits, 2011
In the local circuit of the cerebral cortex, GABAergic inhibitory interneurons are considered to work in collaboration with excitatory neurons. Although many interneuron subgroups have been described in the cortex, local inhibitory connections of each ...

The Sylow subgroups of the symmetric groups [PDF]

Proceedings of the American Mathematical Society, 1955
particular representation by means of "reduced polynomials."' It has seemed worth while to restate some of his results using the concept of complete product L o M of two permutation groups L, M which he and Krasner have recently emphasised.2 This elementary notion is of great importance in the theory of finite groups and it appears in the literature in

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

Advanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Superatom Distortion Induces Triferroicity and Spin Splitting in Two‐Dimensional Antiferromagnets

Advanced Science, EarlyView.
The incorporation of superatoms into a 2D square lattice induces symmetry breaking, thereby enabling concurrent coupling among magnetism, ferroelectricity, and ferroelasticity. This strategy achieves triferroic behavior—characterized by spin‐split antiferromagnetic ground states—and offers a viable pathway toward energy‐efficient spintronic devices ...

An Authenticated Key Agreement Scheme Based on Cyclic Automorphism Subgroups of Random Orders

ITM Web of Conferences, 2017
Group-based cryptography is viewed as a modern cryptographic candidate solution to blocking quantum computer attacks, and key exchange protocols on the Internet are one of the primitives to ensure the security of communication.

A classification of certain maximal subgroups of symmetric groups

Journal of Algebra, 2006
Problem 12.82 of The Kourovka notebook [\textit{V. D. Mazurov} and \textit{E. I. Khukhro} (eds.), The Kourovka notebook. Unsolved problems in group theory. 15th ed., Institute of Mathematics, Novosibirsk (2002; Zbl 0999.20001)] asks for all ordered pairs \((n,m)\) such that the symmetric group \(S_n\) contains a maximal subgroup isomorphic to \(S_m ...

Compact Tabletop Magnetic Resonance Elastography for Mapping Soft Tissue Viscoelasticity

Advanced Science, EarlyView.
This work introduces a compact, low‐cost tabletop magnetic resonance elastography platform for high‐resolution viscoelastic mapping in soft‐tissue specimens. Using this method in human colorectal liver metastases, we demonstrate fully automated biomechanical profiling of treatment response and show that heterogeneity‐based metrics outperform ...

Intersection of Conjugate Solvable Subgroups in Symmetric Groups [PDF]

Algebra and Logic, 2017
It is shown that for a solvable subgroup $G$ of an almost simple group $S$ which socle is isomorphic to $A_n$ $ (n\ge5)$ there are $x,y,z,t \in S$ such that $G \cap G^x \cap G^y \cap G^z \cap G^t =1.$
