4-[Bis(3-phenyl-1H-pyrazol-1-yl)meth-yl]benzene-1,2-diol [PDF]

open access: yes, 2011
The title compound, C25H20N4O2, is a ditopic ortho-hydro­quinone-based bis­(pyrazol-1-yl)methane ligand. The dihedral angles between the planes of the pyrazole rings and their attached phenyl rings are 17.4 (3) and 5.9 (4)°.

Class groups of dihedral extensions [PDF]

open access: yesMathematische Nachrichten, 2005
AbstractLet L/F be a dihedral extension of degree 2p, where p is an odd prime. Let K/F and k/F be subextensions of L/F with degrees p and 2, respectively. Then we will study relations between the p‐ranks of the class groups Cl(K) and Cl(k). (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

ON APPLICATIONS OF THE DIHEDRAL GROUP TO INTERPOLATION PROBLEMS FOR ENTIRE FUNCTIONS

open access: yesПроблемы анализа, 2023
We consider a particular case of the dihedral group of rotations and study linear poly-element functional equations associated with that group. We search for a solution in the class of functions that are holomorphic in the plane with a cut along “half”

Comments on dihedral and supersymmetric extensions of a family of Hamiltonians on a plane

open access: yes, 2010
For any odd $k$, a connection is established between the dihedral and supersymmetric extensions of the Tremblay-Turbiner-Winternitz Hamiltonians $H_k$ on a plane.

Bilangan Kromatik Grap Commuting dan Non Commuting Grup Dihedral

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2015
Commuting graph is a graph that has a set of points X and two different vertices to be connected directly if each commutative in G. Let G non abelian group and Z(G) is a center of G.

Partition numbers of finite solvable groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2018
A group partition is a group cover in which the elements have trivial pairwise intersection. Here we define the partition number of a group - the minimal number of subgroups necessary to form a partition - and examine some of its properties, including ...

Public Key Protocols over Twisted Dihedral Group Rings [PDF]

open access: yes, 2019
Key management is a central problem in information security. The development of quantum computation could make the protocols we currently use unsecure. Because of that, new structures and hard problems are being proposed. In this work, we give a proposal

Algebraic K-theory over the infinite dihedral group: a controlled topology approach

open access: yes, 2011
We use controlled topology applied to the action of the infinite dihedral group on a partially compactified plane and deduce two consequences for algebraic K-theory.

Group Codes Over Dihedral Group Algebras 𝔽q[D16] and 𝔽q[Z2 × D8]

open access: yesJournal of Mathematics
Let Fq denote a finite field of characteristic p, where q=pk for some prime p and integer k. Let Dn represent a dihedral group of order n. In this paper, group codes in the dihedral group algebras FqD16 and FqZ2×D8 are proposed.

Lower algebraic K-theory of certain reflection groups

open access: yes, 2009
For a finite volume geodesic polyhedron P in hyperbolic 3-space, with the property that all interior angles between incident faces are integral submultiples of Pi, there is a naturally associated Coxeter group generated by reflections in the faces ...
