چکیده
|
We consider the application of twistor theory to five-dimensional anti-de sitter space. the twistor space of ads5 is the same as the ambitwistor space of the four-dimensional conformal boundary; the geometry of this correspondence is reviewed for both the bulk and boundary. a penrose transform allows us to describe free bulk fields, with or without mass, in terms of data on twistor space. explicit representatives for the bulk-to-boundary propagators of scalars and spinors are constructed, along with twistor action functionals for the free theories. evaluating these twistor actions on bulk-to-boundary propagators is shown to produce the correct two-point functions.
