Instantons on noncommutative R^4, and (2,0) superconformal six dimensional theory

Abstract

We show that the resolution of moduli space of ideal instantons parameterizes the instantons on non-commutative $\IR^{4}$. This moduli space appears as a Higgs branch of the theory of -branes bound to -branes by the expectation value of the field. It also appears as a regularized version of the target space of supersymmetric quantum mechanics arising in the light cone description of superconformal theories in six dimensions.
