GRAPHS WHOSE AUTOMORPHISM GROUPS CONTAIN THE ALTERNATING GROUPS

, 2019
There have been many investigations on the combinatorial structures and invariants over the group actions on the subsets of its elements. Automorphism groups from Graphs containing the cyclic and dihedral groups, Cn and Dn respectively have been constructed using Schur’s Algorithm.

Quasirecognition by prime graph of some alternating groups

International Journal of Contemporary Mathematical Sciences, 2007
Let G be a finite group. We denote by Γ(G) the prime graph of G. Hagie in (M. Hagie, (2003), The prime graph of a sporadic simple group, Comm. Algebra, 31: 4405-4424) determined finite groups G satisfying Γ(G )=Γ (S), where S is a sporadic simple group. In this paper we determine finite groups G such that Γ(G )=Γ (Ap), where p and p − 2 are primes.

Selective Separation of the Rare Earth Elements Dysprosium and Neodymium via Tailoring Nanocellulose Chemical Structure

Advanced Functional Materials, EarlyView.
Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.

Multi-Attribute Graph Estimation With Sparse-Group Non-Convex Penalties

IEEE Access
We consider the problem of inferring the conditional independence graph (CIG) of high-dimensional Gaussian vectors from multi-attribute data. Most existing methods for graph estimation are based on single-attribute models where one associates a scalar ...

Graph puzzles, homotopy, and the alternating group

Journal of Combinatorial Theory, Series B, 1974
AbstractThe so-called 15-puzzle may be generalized to a puzzle based on an arbitrary graph. We consider labelings or colorings of the vertices and the operation of switching one distinguished label with a label on an adjacent vertex. Starting from a given labeling, iterations of this operation allow one to obtain all, or exactly half, of the labelings ...

Distance transitive graphs with symmetric or alternating automorphism group [PDF]

Bulletin of the Australian Mathematical Society, 1987
The paper classifies all distance transitive graphs Γ such thatAn≤ Aut Γ ≤ AutAnfor some alternating groupAn, and Aut Γ acts primitively on the vertices of Γ. This result forms part of our programme for determining all finite primitive distance transitive graphs.

Exciton‐Polaritons in Nanoscale Metal‐Organic Frameworks: A Platform for the Reversible Modulation of Strong Light‐Matter Coupling via the Chemical Environment

Advanced Functional Materials, EarlyView.
Strong exciton‐photon coupling is achieved by integrating porphyrin ligand‐based MOF nanoparticles in optical cavities, as evidenced by pronounced polariton branch anticrossing. The porous nature of the resonator enables precise, reversible tuning via vapor pressure, unlocking unprecedented chemical‐environment controlled dynamic polaritonic platforms ...

Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

Advanced Functional Materials, EarlyView.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

Generalized matrix functions, determinant and permanent

پژوهش‌های ریاضی, 2022
Introduction Since linear and multilinear algebra has many applications in different branches of sciences, the attention of many mathematicians has been attracted to it in recent decades. The determinant and the permanent are the most important functions

Reliability Analysis of Alternating Group Graphs and Split-Stars

The Computer Journal, 2020
AbstractGiven a connected graph $G$ and a positive integer $\ell $, the $\ell $-extra (resp. $\ell $-component) edge connectivity of $G$, denoted by $\lambda ^{(\ell )}(G)$ (resp. $\lambda _{\ell }(G)$), is the minimum number of edges whose removal from $G$ results in a disconnected graph so that every component has more than $\ell $ vertices (resp. so
