Darboux transformation with dihedral reduction group [PDF]

open access: yes, 2014
We construct the Darboux transformation with Dihedral reduction group for the 2-dimensional generalisation of the periodic Volterra lattice. The resulting Bäcklund transformation can be viewed as a nonevolutionary integrable differential difference ...

Extended symmetry of the Witten-Dijkgraaf-Verlinde-Verlinde equation of Monge-Ampere type [PDF]

open access: yesOpuscula Mathematica
We construct the Lie algebra of extended symmetry group for the Monge-Ampere type Witten-Dijkgraaf-Verlinde-Verlinde (WDVV) equation. This algebra includes novel generators that are unobtainable within the framework of the classical Lie approach and ...

Clifford Group and Unitary Designs under Symmetry

open access: yesPRX Quantum, 2023
We have generalized the well-known statement that the Clifford group is a unitary 3-design into symmetric cases by extending the notion of unitary design.

Orbit Entropy and Symmetry Index Revisited

open access: yesMathematics, 2021
The size of the orbits or similar vertices of a network provides important information regarding each individual component of the network. In this paper, we investigate the entropy or information content and the symmetry index for several classes of ...

Patterned Woven Fabrics in Lithuanian Folk Skirts

open access: yesMedžiagotyra, 2014
In the article 258 Lithuanian folk skirts from National M. K. Čiurlionis Museum of Art and 85 skirts from Lithuanian Open Air Museum are investigated. The weaves and plans of weave of skirts fabrics are made.

Highlights of Symmetry Groups

open access: yes, 2004
The concepts of symmetry and symmetry groups are at the heart of several developments in modern theoretical and mathematical physics. The present paper is devoted to a number of selected topics within this framework: Euclidean and rotation groups; the properties of fullerenes in physical chemistry; Galilei, Lorentz and Poincare groups; conformal ...

Two-loop beta function for complex scalar electroweak multiplets

open access: yesJournal of High Energy Physics, 2020
We present the general form of the renormalizable four-point interactions of a complex scalar field furnishing an irreducible representation of SU(2), and derive a set of algebraic identities that facilitates the calculation of higher-order radiative ...

Structures of coincidence symmetry groups [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2006
The structure of the coincidence symmetry group of an arbitrary n-dimensional lattice in the n-dimensional Euclidean space is considered by describing a set of generators. Particular attention is given to the coincidence isometry subgroup (the subgroup formed by those coincidence symmetries that are elements of the orthogonal group).

What Is the Symmetry Group of a d-PII Discrete Painlevé Equation?

open access: yesMathematics
The symmetry group of a (discrete) Painlevé equation provides crucial information on the properties of the equation. In this paper, we argue against the commonly held belief that the symmetry group of a given equation is solely determined by its surface ...

On triangular (D_{n})-actions on cyclic p-gonal Riemann surfaces [PDF]

open access: yesOpuscula Mathematica, 2016
A compact Riemann surface \(X\) of genus \(g\gt 1\) which has a conformal automorphism \(\rho\) of prime order \(p\) such that the orbit space \(X/ \langle \rho \rangle \) is the Riemann sphere is called cyclic \(p\)-gonal.
