Query: Where do all the supercurvature modes go?   In the hyperbolic slicing of de Sitter space appropriate for open universe
models, a curvature scale is present and supercurvature fluctuations are
possible. In some cases, the expansion of a scalar field in the Bunch-Davies
vacuum includes supercurvature modes, as shown by Sasaki, Tanaka and Yamamoto.
We express the normalizable vacuum supercurvature modes for a massless scalar
field in terms of the basis modes for the spatially-flat slicing of de Sitter
space.
