چکیده
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.

Topological Charge of ADHM Instanton on RNC × R
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) insta...
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 کاملRecent Developments in Instantons in Noncommutative R4
We review recent developments in noncommutative deformations of instantons in R4. In the operator formalism, we study how to make noncommutative instantons by using the ADHM method, and we review the relation between topological charges and noncommutativity. In the ADHM methods, there exist instantons whose commutative limits are singular. We review smooth noncommutative deformations of instant...
متن کاملhep - th / 0109111 Elongated U ( 1 ) Instantons on Noncommutative R 4
We found an exact solution of elongated U(1) instanton on noncommutative R for general instanton number k. The deformed ADHM equation was solved with general k and the gauge connection and the curvature were given explicitly. We also checked our solutions and evaluated the instanton charge by a numerical calculation.
متن کاملInstanton Number Calculus on Noncommutative R
In noncommutative spaces, it is unknown whether the Pontrjagin class gives integer, as well as, the relation between the instanton number and Pontrjagin class is not clear. Where we define “Instanton number” by the size of Bα in the ADHM construction. We show the analytical derivation of the noncommuatative U(1) instanton number as an integral of Pontrjagin class (instanton charge) with the Foc...
