Description
I review the construction of maximal supergravities in two dimensions. These are parametrized by an embedding tensor transforming in the basic representation of the affine algebra E9. Among the examples is the SO(9) theory describing the low-energy effective action upon reduction of the type IIA theory on the D0-brane near-horizon geometry.
