Description
A major application of extended geometries in supergravity is
the construction of consistent truncations. Remarkably, all this
construction's ingredients also appear in the context of generalised T-
and U-dualities. After a quick review of both concepts, I will discuss a
conjectured correspondence between consistent truncations and
generalised dualities in string and M-theory. We will prove that all
known generalised dualities give rise to consistent truncations.
Moreover, we will see evidence that after incorporating higher
derivative correction, all consistent truncations might be based on
generalised dualities.
