the quasi-periodic order is a type of geometrical order in universe which is observed in the structure of quasi-crystals. this order was first introduced in mathematics in 1973 by roger penrose and then discovered in quasi-crystals in 1984 while spreading in mathematics, chemistry and physics. the paper professor james lu et al published in science magazine in 2007 illustrated that iranians wer...

This editorial is a short review of papers accepted in the Mathematics and Symmetry/Asymmetry section 2020–2021 about symmetry methods [...]

In 2002, a method has been proposed by Buchholz et al. in the context of Local Quantum Physics, to characterize states that are locally in thermodynamic equilibrium. It could be shown for the model of massless bosons that these states exhibit quite interesting properties. The mean phase-space density satisfies a transport equation, and many of these states break time reversal symmetry. Moreover...

in recent years, mathematics is an essential aspect of all areas of daily life and the best predictor of being successful in economic situations of society. for many students, the mathematics accompanied with frustration, anxiety and negative attitudes towards mathematics. these students believe their anxiety have been derived from their math teachers, math misconception and weakness in math as...

Symmetry has been dealt with in a wide variety of elds in both art and science. Symmetry and asymmetry as aesthetic features have been used in architecture, sculptures and paintings. Symmetry and symmetric groups have been de ned in mathematics [31]. Symmetry and it's compliment feature Chirality are basic properties of molecular structure that mediate chemical properties [29]. Though symmetry ...

or perhaps with the face of our mother or father. We quickly learn to identify the axis of symmetry and know intuitively that an object is symmetric if it “the same” on both sides of this axis. In mathematics symmetry is abundant and takes many forms. Symmetry like that of the butterfly or a face is referred to as reflexive symmetry. Any line in the plane determines a unique symmetry which refl...

Symmetry constraints for dispersionless integrable equations are discussed. It is shown that under symmetry constraints the dispersionless Veselov-Novikov equation is reduced to the 1+ 1-dimensional hydrodynamic type systems. Mathematics Subject Classification. 35Q58, 37K15, 37K20.
