G_2-instantons on the 7-sphere
1 Oxford Street, Cambridge, MA 02138 USAAbstract:
I’ll discuss a forthcoming paper studying families of G_2-instantons on S^7, focusing on those which are obtained by pulling back asd instantons on S^4 via the quaternionic Hopf fibration. In the charge-1 case, this yields a smooth and complete 15-dimensional family. The situation for the higher charge is more complicated, but we are able to compute all the infinitesimal deformations.
