Dual Actions for Chiral Bosons
Alexey Maznytsia, Christian R. Preitschopf, Dmitri Sorokin
We study duality properties of actions for chiral boson fields in various space-time dimensions using D=2 and D=6 cases as examples. As a result we get dual covariant formulations…
The Superalgebraic Approach to Supergravity
C. R. Preitschopf, M. A. Vasiliev
We formulate classical actions for N=1 supergravity in D=(1,3) as a gauge theory of OSp(1|4). One may choose the action such that it does not include a cosmological term.
Octonions and Supersymmetry
C. R. Preitschopf
We apply the techniques of -algebras to the construction of N=5-8 superconformal algebras and of S{\bf O}(1,9), a modification of SO(1,9) which commutes with -transformat…
Current Algebras
Martin Cederwall, Christian R. Preitschopf
We present -algebras as generalized Kac-Moody algebras. A number of free-field representations is found. We construct the octonionic projective spaces .
