- Descrição
- Higher dimensional Majorana-Weyl spacetimes present space-time dualities which are induced by the Spin(8) triality automorphisms. Di erent signature versions of theories such as 10-dimensional SYM's, superstrings, ve-branes, F-theory, are shown to be interconnected via the S3 permutation group. Bilinear and trilinear invariants under spacetime triality are introduced and their possible relevance in building models possessing a space-versus-time exchange symmetry is discussed. Moreover the Cartan's \vector/chiral spinor/antichiral spinor" triality of SO(8) and SO(4; 4) is analyzed in detail and explicit formulas are produced in a Majorana-Weyl basis. This paper is the extended version of hep-th/9907148.
