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…

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.
