Extensions, expansions, Lie algebra cohomology and enlarged superspaces
After briefly reviewing the methods that allow us to derive consistently new Lie (super)algebras from given ones, we consider enlarged superspaces and superalgebras, their relevance and some possible applications.
On the underlying gauge group structure of D=11 supergravity
The underlying gauge group structure of D=11 supergravity is revisited (see paper for detailed abstract).
