Talk title: On enlarged superspaces: structure and applications
Abstract:
We argue that a suitable description of superstring-M-theory
from a unified geometric point of view requires considering
enlarged superspaces. We discuss very briefly how to obtain
(super)algebras from another ones (by extension, contraction,
deformation as well as by the novel expansion procedure), the idea
of fields/extended superspace democracy, the derivation of the
M-algebra as an expansion of osp(1|32), and CS supergravity.
