Instantons in gauge theories: solutions of Euclidean equations of motion. Sad- dle points of path integrals. Instantons as self-dual connections. The k = 1 solution. This volume is a compilation of works which, taken together, give a complete and consistent presentation of instanton calculus in non-Abelian gauge theories. 13 Feb First the basics are derived from scratch: the regular and singular one-instanton solutions for Yang-Mills theories with gauge groups SU(2) and.
In N = 1 supersymmetric gauge theories instantons can modify the superpotential , sometimes lifting all of the. 10 Jan Instantons in supersymmetric gauge theories. Tobias Hansen.

22 May A gauge theory can be formulated on a noncommutative (NC) spacetime. This NC gauge theory has an equivalent dual description through the. We review the definition of instanton (= pseudoparticle) solutions and their importance in the context of nonabelian gauge (= Yang-Mills) theories, as well as the. Instantons in gauge theories with. N=1/2 supersymmetry. Oleg Lunin. Institute for Advanced Study. R. Britto, B. Feng, O. L., S–J. Rey, hep-th/ USA Received 29 January We extend a previously formulated instanton superfield method from SU(2) to SU(W) gauge theories without classical vacuum . The topological data for such instanton bundles and their relations to the quiver gauge theories are described. Based on such gauge theory constructions, we.
Glimm, James; Jaffe, Arthur. Instantons in a U (1) lattice gauge theory: a Coulomb dipole gas. Comm. Math. Phys. 56 (), no. 3, A linguistic remark: "Instantons" are the same mathematically to "solitons", particle-like solutions of classical field theories (explaining the suffix. Someone may suggest I post this on PhysicsSE, but I would prefer to not have a physicist answer in jargon I cannot understand. In fact, the. Instantons are a particularly tractable class of non-perturbative configurations of gauge theories leading to many effects at strong coupling in QCD (e.g., U(1).
