Symmetry group, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation
In this paper Lie point symmetries, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation are investigated. First of all Lie symmetries are obtained by using the general method based on invariance condition of a system of differential equations under a prolonged vector field. Then the structure of symmetry ...
متن کاملOrbits of crystallographic embedding of non-crystallographic groups and applications to virology.
The architecture of infinite structures with non-crystallographic symmetries can be modelled via aperiodic tilings, but a systematic construction method for finite structures with non-crystallographic symmetry at different radial levels is still lacking. This paper presents a group theoretical method for the construction of finite nested point sets with non-crystallographic symmetry. Akin to th...
متن کاملAlgorithms for deriving crystallographic space-group information. II. Treatment of special positions.
Algorithms for the treatment of special positions in three-dimensional crystallographic space groups are presented. These include an algorithm for the determination of the site-symmetry group given the coordinates of a point, an algorithm for the determination of the exact location of the nearest special position, an algorithm for the assignment of a Wyckoff letter given the site-symmetry group...
متن کاملCSDSymmetry: the definitive database of point-group and space-group symmetry relationships in small-molecule crystal structures.
An algorithm that perceives molecular symmetry has been applied to ca. 200,000 entries from the Cambridge Structural Database (CSD). For each molecule, the perceived point group, together with crystallographic properties such as space group, occupied Wyckoff positions and number of residues in the asymmetric unit, have been placed in a relational database, CSDSymmetry, using Microsoft Access so...
متن کاملTwo-Dimensional Symmetry Mutation
Although the crystallographic notation for two-dimensional Eu-clidean and spherical symmetry groups is widely used, Conway's orbifold notation is both simpler and more transparent, and provides a uniied naming scheme for symmetry groups of all three two-dimensional geometries. Based on it, this paper dicusses the concept of symmetry mutation, an operation that maps a two-dimensional symmetry gr...
