The antibracket formalism for gauge theories, at both the classical and quantum level, is reviewed. Gauge transformations and the associated gauge structure are analyzed in detail. The basic concepts involved in the antibracket formalism are elucidat

If certain long-ranged interactions between instantons are present, the θ parameter relaxes to zero. The question is raised as to whether this can happen in Yang-Mills theory thereby leading to a natural solution of the strong CP problem. A lattice

We define new lattices called d-dimensional twisted group lattices. They are similar to ordinary lattices except that abstract screw dislocations are present at the centers of all plaquettes. Some physical aspects are enumerated. We consider the stat

Three topics in bosonic technicolor are treated from the viewpoint of the renormalization group: coupling constant unification, linking of the supersymmetry-breaking and technicolor scales, and a naturally light up-Higgs.

Four-dimensional twisted group lattices are used as models for space-time structure. Compared to other attempts at space-time deformation, they have two main advantages: They have a physical interpretation and there is no difficulty in putting field

An investigation is undertaken for 't Hooft loop operators in four-dimensional gauge theories. For the first time, a perimeter law is shown to be their behavior in weak coupling Wilson lattice (and continuum) non-abelian SU( N ) gauge theories for al

Formulas for the evaluation of all U(N) integrals are derived. Tables display the results for integrands involving up to six U’s and six U°’s. The complete pole structure of De Wit–’t Hooft anomalies is unveiled. The effects of 1/N2 correcti

The average action per plaquette is calculated using strong-coupling expansions up to 15th order for the pure U(N), N = 2, 3, 4, 5, and 6, four-dimensional Euclidean lattice gauge theory. We compare these expansions with Monte Carlo-generated data an

Integrals over anticommuting variables are use to rewrite partition functions as fermionic field theories. The method is used to solve the two‐dimensional Ising model, the planar close‐packed dimer problems, and the free‐fermion eight vertex mo

Two-dimensional chiral models are investigated from a strong coupling viewpoint, with the ultimate objective of understanding the phase structure of gauge theories. Predictions for the average link and beta function are obtained. The abelian case agr
