D-instantons and Matrix Models
arXiv:hep-th/9903050 · doi:10.1088/0264-9381/16/10/308
Abstract
We discuss the Matrix Model aspect of configurations saturating a fixed number of fermionic zero modes. This number is independent of the rank of the gauge group and the instanton number. This will allow us to define a large- limit of the embeddeding of D-instantons in the Matrix Model and make contact with the leading term (the measure factor) of the supergravity computations of D-instanton effects. We show that the connection between these two approaches is done through the Abelian modes of the Matrix variables.
