Isocanted cube: the lower Lebesgue volumes, incidence numbers and symmetries of this d–dimensional tile

open access: yesExtracta Mathematicae
Let d ≥ 2. In this paper we prove that Id(ℓ, a) fills Rd face–to–face by translations. We prove that the symmetry group of Id(ℓ, a) contains the product of cyclic groups Cd × C2 as a subgroup.

Targeting high symmetry in structure predictions by biasing the potential energy surface

open access: yesPhysical Review Research, 2023
Ground-state structures found in nature are, in many cases, of high symmetry. But structure prediction methods typically render only a small fraction of high-symmetry structures.

Symmetry of benzenoid chains

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2006
Graph theory provides an elegant and natural representation of molecular symmetry and the resulting group expressed in terms of permutations is isomorphic to the permutation-inversion group of Longuet-Higgins.

Dihedral Group in The Ancient Genetic

open access: yesJurnal Matematika Integratif, 2020
The standard genetic code consist of four nucleotide bases which encode genes to produce amino acids needed by living things. The addition of new base  (Dummy) causes a sequence of bases to become five nucleotide bases called ancient genetic codes.

An optimal system of one-dimensional subalgebras for the symmetry algebra of three-dimensional equations of the perfect plasticity

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The present paper is devoted to a study of a natural 12-dimensional symmetry algebra of the three-dimensional hyperbolic differential equations of the perfect plasticity, obtained by D. D. Ivlev in 1959 and formulated in isostatic coordinates. An optimal

Symmetry group analysis and invariant solutions of hydrodynamic-type systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We study point and higher symmetries of systems of the hydrodynamic type with and without an explicit dependence on t,x. We consider such systems which satisfy the existence conditions for an infinite-dimensional group of hydrodynamic symmetries which ...

Extended topological group structure due to average reflection symmetry

open access: yesNew Journal of Physics, 2015
We extend the single-particle topological classification of insulators and superconductors to include systems in which disorder preserves average reflection symmetry.

The Language of Spheres in Physics

open access: yesUniverse
Physical laws manifest themselves through the amalgamation of mathematical symbols, numbers, functions, geometries, and relationships. These intricate combinations unfold within a mathematical model devised to capture and represent the “objective reality”
