Triality Invariance in the N=2 Superstring
Leonardo Castellani, Pietro Antonio Grassi, Luca Sommovigo
We prove the discrete triality invariance of the N=2 NSR superstring moving in a D=2+2 target space. We find that triality holds also in the Siegel-Berkovits formulation of the sel…

Noncommutative supergravity in D=3 and D=4
Paolo Aschieri, Leonardo Castellani
We present a noncommutative D=3, N=1 supergravity, invariant under diffeomorphisms, local U(1,1) noncommutative \star-gauge transformations and local \star-supersymmetry. Its commu…

Noncommutative D=4 gravity coupled to fermions
Paolo Aschieri, Leonardo Castellani
We present a noncommutative extension of Einstein-Hilbert gravity in the context of twist-deformed space-time, with a -product associated to a quite general triangular Drinf…
