"Deformations of Nearly G_2 instantons - Part 2"

In this talk we will discuss the deformation theory for instantons on  seven-manifolds with nearly parallel G_2-structure of type-I. We will see how the space of perturbations of instantons can be identified with the eigenspaces of the Dirac operatior, which can be used to prove that all the irreducible instantons with semisimple structure group are rigid.
