Complementary ADHM Instanton Sigma Model
arXiv:2305.05951
Abstract
We construct the ADHM linear sigma model that is complementary to a model constructed by Edward Witten in 1995. Analysis of the corresponding moduli space leads to the resolution of a nearly three decade old mystery associated with the original construction. A number of problems are listed on which this construction has a bearing.
