Ramond–Ramond potential (source code)

= Ramond–Ramond potential
{c}
{title2=$C_p$}

A differential-form <gauge potential> from the <Ramond–Ramond sector>. A <D-brane> carries electric or magnetic charge under the appropriate potential. Circle reduction of the M-theory metric gives the IIA one-form potential, while its three-form gives the IIA three-form potential.
