Gradings on the simple real Lie algebras of types $G_2$ and $D_4$ (1803.10949v1)

Abstract: We classify group gradings on the simple Lie algebras of types $G_2$ and $D_4$ over the field of real numbers (or any real closed field): fine gradings up to equivalence and $G$-gradings, with a fixed group $G$, up to isomorphism.
