"... Symmetry BreakingThe front cover shows quantum mechanics (symbolized by Schrödinger’s cat) playing withthe Higgs-field in the Mexican hat potential. The back cover shows the Maxwell construction of the Mexican hat potential, which is obtained in the path-integral approach to the N = 2 linear sigma m ..."

Symmetry Breaking in

by Su Theta Erez-Lorenzana, Theta Z, D. E. Jaramillo, William A. Ponce, Arnulfo Zepeda
"... .We analize the different ways for the spontaneous breaking of the gauge symmetry, for the [SU (6)] 3\Omega Z 3 family unification model. In particular we study the consequences of a previous selection for the vacuum expectation values of the Higgs fields, showing that such set predicts unwanted f ..."

Symmetry-Breaking Predicates for Search Problems

by James Crawford , Matthew Ginsberg, Eugene Luks, Amitabha Roy , 1996
"... Many reasoning and optimization problems exhibit symmetries. Previous work has shown how special purpose algorithms can make use of these symmetries to simplify reasoning. We present a general scheme whereby symmetries are exploited by adding "symmetry-breaking" predicates to the the ..."

Symmetries of Symmetry Breaking Constraints

by George Katsirelos, Toby Walsh
"... Symmetry is an important feature of many constraint programs. We show that any symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different symmetries pick out different solutions in each symmetry class. We use these observations in two methods for eliminating s ..."

Dynamic Symmetry Breaking Constraints

by George Katsirelos , Toby Walsh , 2008
"... We present a general method for dynamically posting symmetry breaking constraints during search. The basic idea is very simple. Given any set of symmetry breaking constraints, if during search a symmetry of one of these constraints is entailed and this is consistent with previously posted symmetry ..."
