A Symmetry Index for Graphs
This note introduces a quantitative measure (S(G)) of the symmetry structure of a graph G. S(G) is called the index of symmetry of G and is a function of its structural information content and the order of its automorphism group. Properties of S(G) are examined and applications to special classes of graphs are presented. In particular, the index of symmetry of a class of alkanes is shown to be ...
متن کاملSymmetric Spaces with Conformal Symmetry
We consider an involutive automorphism of the conformal algebra and the resulting symmetric space. We display a new action of the conformal group which gives rise to this space. The space has an intrinsic symplectic structure, a group-invariant metric and connection, and serves as the model space for a new conformal gauge theory. ∗Electronic-mail: [email protected]
متن کاملSymmetry-Based Façade Repair
In this paper we address the problem of removing unwanted image content in a single orthographic façade image. We exploit the regular structure present in building façades and introduce a diffusion process that is guided by the symmetry prevalent in the image. It removes larger unwanted image objects such as traffic lights, street signs, or cables as well as smaller noise, such as reflections i...
متن کاملOutcomes of Reoperation After Acute Type A Aortic Dissection: Implications for Index Repair Strategy
BACKGROUND The optimal surgical approach for management of acute type A aortic dissection remains controversial. This study aimed to assess outcomes of reoperation after acute type A dissection repair to help guide decision making around index operative strategy. METHODS AND RESULTS All aortic reoperations (n=129) at a single referral institution from August 2005 to April 2016 after prior acu...
متن کاملSymmetric Unimodality Index
A conformal partition function Pm n (s), which arised in the theory of Diophantine equations supplemented with additional restrictions, is concerned also with the reciprocal and skew-reciprocal algebraic equations based on the polynomial invariants of the symmetric group Sn. Making use of the relationship between Gaussian generating function for conformal partitions and Molien generating functi...
