Topological Charge of ADHM Instanton on RNC × R
نویسنده
چکیده
We have calculated the topological charge of U(N) instantons on non-degenerate noncommutative space time to be exactly the instanton number k in a previous paper [1]. This paper, which deals with the degenerate R NC ×R2 case, is the continuation of [1]. We find that the same conclusion holds in this case, thus complete the answer to the problem of topological charge of noncommutative U(N) instantons.

Topological Charge of Noncommutative ADHM Instanton
We analytically calculate the topological charge of the noncommutative ADHM U(N) k-instanton using the Corrigan’s identity and find that the result is exactly the instanton number k.
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]....
متن کاملNoncommutative Moduli for Multi-Instantons
There exists a recursive algorithm for constructing BPST-type multi-instantons on commutative R. When deformed noncommutatively, however, it becomes difficult to write down non-singular instanton configurations with topological charge greater than one in explicit form. We circumvent this difficulty by allowing for the translational instanton moduli to become noncommutative as well. This makes p...
متن کاملInstantons and the Buckyball
The study of Skyrmions predicts that there is an icosahedrally symmetric charge seventeen SU(2) Yang-Mills instanton in which the topological charge density, for fixed Euclidean time, is localized on the edges of the truncated icosahedron of the buckyball. In this paper the existence of such an instanton is proved by explicit construction of the associated ADHM data. A topological charge densit...
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...
