Possible Schemes for Global Symmetry

Journal of Mathematical Physics, 1963
An attempt was made to determine all possible schemes for global symmetry as representations of groups. All possible schemes which correspond to connected groups were found, but the conclusions about nonconnected groups are incomplete. Physical interpretation of the schemes is discussed, and a detailed summary of group-theoretic methods is included.

Test on the global symmetry

Il Nuovo Cimento, 1958
A possible test of the global symmetry proposed independently by Gell- Mann. Schwinger, and Tiomno is discussed. The discussion is confined to the case of final three-body reactions where the conservation of energy and angular momentum appear less restrictive for a pair among the final three particles.

Concurrent Symmetries: The Interplay Between Local and Global Molecular Symmetries

Chemistry – A European Journal, 2010
AbstractWe analyze in this article the degree to which different groups of atoms retain local symmetries when assembled in a molecule. This study is carried out by applying continuous symmetry measures to several families of mixed sandwiches, a variety of piano‐stool molecules, and several organic groups.

Global Symmetry, Local Symmetry, and the Lattice

2010
Confinement in non-abelian gauge theory involves the idea that the vacuum state is disordered at large scales; our best evidence that this is true comes from Monte Carlo simulations of lattice gauge theories. So to begin with, I need to explain what is meant by a disordered state, a lattice gauge theory, a Monte Carlo simulation.

Weak global symmetry

Il Nuovo Cimento, 1960
The Feynman, Gell-Mann model of weak interactions is modified by the introduction of neutral « currents », both of the strangenesss preserving (J) and strangeness changing (S) variety. The various currents, neutral and charged, are chosen and coupled in such a manner as to guarantee the |ΔT|=1/2 selection rule.

Group Representation of Global Intrinsic Symmetries

Computer Graphics Forum, 2017
AbstractGlobal intrinsic symmetry detection of 3D shapes has received considerable attentions in recent years. However, unlike extrinsic symmetry that can be represented compactly as a combination of an orthogonal matrix and a translation vector, representing the global intrinsic symmetry itself is still challenging.

Global Cut Framework for Removing Symmetries

2001
In this paper, we propose a general technique for removing symmetries in CSPs during search. The idea is to record no-goods, during the exploration of the search tree, whose symmetric counterpart (if any) should be removed. The no-good, called Global Cut Seed (GCS), is used to generate Symmetry Removal Cuts (SRCs), i.e., constraints that are ...

Symmetry and Scale: From Local to Global Symmetries

1989
The explanation of the properties of macroscopic bodies and large-scale phenomena by exploring the features of the microscopic constituents is one of the oldest paradigms of physical sciences. Among the features which are perhaps the most obvious and often the most intriguing are the observed symmetries of material objects.
