"Deformations of Nearly G₂ Instantons"

In this talk we will discuss the deformation theory for instantons on  seven-manifolds with nearly parallel G₂-structure of type-I. We will see how the space of perturbations of instantons can be identified with the eigenspaces of the Dirac operator, which can be used to prove that all the irreducible instantons with semisimple structure group are rigid.
