Lie symmetry analysis for Kawahara-KdV equations

We introduce a new solution for Kawahara-KdV equations. The Lie group analysis is used to carry out the integration of this equations. The similarity reductions and exact solutions are obtained based on the optimal system method.

On Symmetry of Some Nano Structures

It is necessary to generate the automorphism group of a chemical graph in computer-aided structure elucidation. An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix M = [dij], where for i≠j, dij is the Euclidean distance between the nuclei i and j. In this matrix dii can be taken as zero if all the nuclei are equivalent. Otherwise, one may introduce...

Symmetry impedes symmetry discrimination.

Objects in the world, natural and artificial alike, are often bilaterally symmetric. The visual system is likely to take advantage of this regularity to encode shapes for efficient object recognition. The nature of encoding a symmetric shape, and of encoding any departure from it, is therefore an important matter in visual perception. We addressed this issue of shape encoding empirically, notin...

a symmetry of power in michelangelo’s moses

among the various interpretations of michelangelo’s moses, freud’s is well-known. the founder of psychoanalysis, freud reviews all the critics and interpretations of this masterpiece and then offers his own: this moses is not about to spring up, as claimed by others, but on the contrary, is sitting down, suppressing his “rage”. in the light of recent works of daniel arasse, art critic (study of...
