Abstract
In this letter we describe how to string together the
doubled field approach by Cremmer, Julia, Lüand Pope with
Pasti-Sorokin-Tonin technique to construct the sigma-model-like
action for type IIA supergravity. The relation of the results with
that of obtained in the context of searching for
Superstring/M-theory hidden symmetry group is discussed.
