# Manifolds with special holonomy especially $G_2$

I am interested in learning about $G_2$ manifolds and am aware that one of the canonical references is Joyce's Compact Manifolds with Special Holonomy. I am certain that my background is, at this moment, not enough to read this research monograph so I would like to know if there are books that can bring me up to speed. My background is in Lee and Do Carmo level.

• There are currently ongoing efforts on the classification of G2 manifolds. These slides seem to give a nice introductory overview of the subject. Here are a few papers on new invariants and the likes. From here googling the authors should bring up more resources and eventually some books. Jan 8, 2017 at 15:15
