Self-Dual and Anti-Self-Dual Gauge Fields| Self-Dual and Anti-Self-Dual Gauge Fields |
In General
> s.a. integrable systems; yang-mills gauge theory.
$ Def: Solutions of the Yang-Mills equations
such that \(F_{ab} = \pm\, ^*F_{ab}\); > s.a. duality
in field theories.
* Alternative characterization: Self-dual
Yang-Mills equations are equivalent to the consistency conditions for the system
(Dy − ξ Dv) ψ = 0 , (Du − ξ Dz) ψ = 0 .
* Motivation: They minimize the action.
* Symmetry reductions:
They give integrable systems [@ Ward PTRS(85)]; In the stationary axisymmetric case, one gets the Ernst equation
[@ Witten PRD(79)];

* Construction: One can get
an anti-self-dual connection on an SU(2) bundle as follows; Start with the
SU(2)-bundle over S4 defined by the Hopf
fibration; The standard metric on S7
defines a connection A on it; If s is the south pole of
S4, define the inverse stereographic
projection ψ: \(\mathbb R\)4
→ S4 \ {s}; Then
φ* A defines
the anti-self-dual SU(2) connection.
