Topological Yang Mills and Instantons
نویسندگان
چکیده
By defining an extended BRST operator that includes the chiral part of N=2 global supersymmetry, it is shown that the full N=2 offshell Super Yang Mills Action can be represented as an exact BRST term. The action written in this form suggests that the fields of the Topological Yang Mills theory can be defined in terms of composite fields of supersymmetry ghosts and N=2 fields in a natural way. Topological Yang Mills theory is obtained from the ordinary Euclidean N=2 SYM directly as field redefinitions without using twisting procedure. With the help of these results, relation between the recent instanton calculations in N=2 Super Yang Mills and Topological Yang Mills theories is also discussed. e-mail: [email protected]

Deformed Instantons
In this talk, instantons are discussed in the presence of Lorentz violation. Conventional topological arguments are applied to classify the modified solutions to the Yang-Mills equations according to the topological charge. Explicit perturbations to the instantons are calculated in detail for the case of unit topological charge.
متن کاملInstantons and Quaternions
We relate the moduli space of Yang-Mills instantons to quaternionic manifolds. For instanton number one, the Wolf spaces play an important role. We apply these ideas to instanton calculations in N = 4 SYM theory. Instantons in Yang-Mills theories are defined by the solutions to the self-duality equation in four-dimensional Euclidean space, Fμν = Fμν = 1 2ǫμνρσFρσ , (1) and are characterized by ...
متن کاملAspects of N T ≥ 2 Topological Gauge Theories and D-branes
We comment on various aspects of topological gauge theories possessing N T ≥ 2 topological symmetry: 1. We show that the construction of Vafa-Witten and Dijkgraaf-Moore of 'bal-anced' topological field theories is equivalent to an earlier construction in terms of N T = 2 superfields inspired by supersymmetric quantum mechanics. 2. We explain the relation between topological field theories calcu...
متن کاملN = 2 Strings and the Twistorial Calabi-yau
We argue that open N = 2 string theory on spacetime with signature (2, 2), when covariantized with respect to SO(2, 2) and supersymmetrized a la Siegel, becomes equivalent to the topological A model on CP3|4 with branes wrapped on RP3|4. Worldsheet instantons ending on the branes deform the self-dual Yang-Mills to ordinary Yang-Mills. Moreover, we propose that mirror symmetry may explain the re...
متن کاملN = 2 Super Yang-mills Action as a Becchi-rouet-stora-tyutin Term, Topological Yang-mills Action and Instantons
By constructing a nilpotent extended BRST operator ¯ s that involves the N=2 global supersymmetry transformations of one chirality, we show that the standard N=2 off-shell Super Yang Mills Action can be represented as an exact BRST term ¯ sΨ, if the gauge fermion Ψ is allowed to depend on the inverse powers of supersymmetry ghosts. By using this nonanalytical structure of the gauge fermion (via...
