The classification of ERP G2-structures on Lie groups
Jorge Lauret, Marina Nicolini
A complete classification of left-invariant closed G2-structures on Lie groups which are extremally Ricci pinched, up to equivalence and scaling, is obtained. There are five of the…

Extremally Ricci pinched G2-structures on Lie groups
Jorge Lauret, Marina Nicolini
Only two examples of extremally Ricci pinched G2-structures can be found in the literature and they are both homogeneous. We study in this paper the existence and structure of such…
