A generalization of the notion of tangent bundle in exceptional generalized geometry.
For 11-dimensional supergravity the bosonic body of its typical fiber is
where the second summand corresponds to M2-brane charges and the third to M5-brane charges.
This happens to coincide with the bosonic body of the M-theory super Lie algebra, see there for more.
(…)
The notion is already recognizable in
via KK-reduction of the “M-algebra”.
It became more widely appreciated under the heading “exceptional generalized geometry” with:
The actual term “exceptional tangent bundle” appears, in the context of exceptional field theory, for instance in
