Dual instantons

چکیده
We show how to map the Belavin-Polyakov instantons of the O(3)-nonlinear sigma model to a dual theory where they then appear as nontopological solitons. They are stationary points of the Euclidean action in the dual theory, and moreover, the dual action and the O(3)-nonlinear sigma model action agree on shell.

Geometric interpretation of Schwarzschild instantons
In this note we address the problem of finding Abelian instantons of finite energy on the Euclidean Schwarzschild manifold. This amounts to construct self-dual L2 harmonic 2-forms on the space. Gibbons found a non-topological L2 harmonic form in the Taub-NUT metric, leading to Abelian instantons with continuous energy. We imitate his construction in the case of the Euclidean Schwarzschild manif...
متن کاملADHM Construction of Instantons on the Torus
We apply the ADHM instanton construction to SU(2) gauge theory on Tn × R 4−n for n = 1, 2, 3, 4. To do this we regard instantons on Tn × R 4−n as periodic (modulo gauge transformations) instantons on R . Since the R 4 topological charge of such instantons is infinite the ADHM algebra takes place on an infinite dimensional linear space. The ADHM matrix M is related to a Weyl operator (with a sel...
متن کاملNoncommutative Instantons on R
We study U(1) and U(2) noncommutative instantons on RNC ×RC based on the ADHM construction. It is shown that the instanton solutions are always regular for both self-dual and anti-self-dual gauge fields even though any projected states are not involved in the ADHM construction. Furthermore the instanton number is also an integer. [email protected] [email protected] [email protected]....

Self-dual instantons in S2 − × S 2 + are studied, where S 2 − × S 2 + is the conformal compactification of the semi-Euclidean space R2+2.
متن کاملMulti-instantons in seven dimensions
We consider the self-dual Yang-Mills equations in seven dimensions. Modifying the t’Hooft construction of instantons in d = 4, we find N -instanton 7d solutions which depend on 8N effective parameters and are E6-invariant.
