Common Neighborhood Energy of the Non-Commuting Graphs and Commuting Graphs Associated with Dihedral and Generalized Quaternion Groups

Mathematics
This paper explores the common neighborhood energy (ECN(Γ)) of graphs derived from the dihedral group D2n and generalized quaternion group Q4n, specifically the non-commuting graph (NCM-graph) and the commuting graph (CM-graph).

Universal deformation rings and dihedral 2-groups

, 2008
Let $k$ be an algebraically closed field of characteristic 2, and let $W$ be the ring of infinite Witt vectors over $k$. Suppose $D$ is a dihedral 2-group. We prove that the universal deformation ring $R(D,V)$ of an endo-trivial $kD$-module $V$ is always

Orthogonal bases of Brauer symmetry classes of tensors for groups having cyclic support on non-linear Brauer characters

, 2015
This paper provides some properties of Brauer symmetry classes of tensors. We derive a dimension formula for the orbital subspaces in the Brauer symmetry classes of tensors corresponding to the irreducible Brauer characters of the groups having cyclic ...

Shunkov Groups with Additional Finiteness Conditions, Containing Dihedral Subgroups

Известия Иркутского государственного университета: Серия "Математика"
In this paper, Shunkov groups are studied in the context of the well-known question of B. Amberg and L. S. Kazarin about the structure of groups containing direct products of a finite number of dihedral groups.

N,N′-Bis(2-furylmethylene)-1,1′-binaphthyl-2,2′-diamine

Acta Crystallographica Section E, 2008
In the title compound, C30H20N2O2, the orientation of the furyl group may induce a variety of coordination modes with this ligand. The dihedral angle between the two naphthyl rings is 79.25 (7)°.

Algebras and Dihedral Defect Groups

Proceedings of the London Mathematical Society, 1987
Let F be an algebraically closed field of characteristic 2, and let G be a finite group. Let B be a block of the group algebra FG with dihedral defect group D of order \(2^ n\). It has been proved by \textit{R. Brauer} [Symp. Math. 13, 367-393 (1974; Zbl 0288.20010)] that B has either 1, 2 or 3 simple modules.

On pointed Hopf algebras over dihedral groups

, 2010
Let k be an algebraically closed field of characteristic 0 and let D_m be the dihedral group of order 2m with m= 4t, with t bigger than 2. We classify all finite-dimensional Nichols algebras over D_m and all finite-dimensional pointed Hopf algebras whose

Classification Formula and Generation Algorithm of Cycle Decomposition Expression for Dihedral Groups

Abstract and Applied Analysis, 2013
The necessary of classification research on common formula of group (dihedral group) cycle decomposition expression is illustrated. It includes the reflection and rotation conversion, which derived six common formulae on cycle decomposition expressions ...

Dihedral Gauss hypergeometric functions

, 2011
Gauss hypergeometric functions with a dihedral monodromy group can be expressed as elementary functions, since their hypergeometric equations can be transformed to Fuchsian equations with cyclic monodromy groups by a quadratic change of the argument ...

Dihedral defect groups

Journal of Algebra, 1979
AbstractThis paper determines much of the structure of blocks whose defect group is dihedral, semidihedral or generalised quaternion and which have either one or two simple modular representations (Brauer characters). It is shown that in the above circumstances there is only a very small number of possibilities for the Cartan matrix, decomposition ...
