Topological Charge of Noncommutative ADHM Instanton

arXiv:hep-th/0211225 · doi:10.1142/S0217732303011411

Abstract

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.
