Query: Covariant Description of D-branes in IIA Plane-Wave Background   We work out boundary conditions for the covariant open string in the type IIA
plane wave background, which corresponds to the D-branes in the type IIA
theory. We use the kappa symmetric string action and see what kind of boundary
conditions should be imposed to retain kappa symmetry. We find half BPS as well
as quarter BPS branes and the analysis agrees with the previous work in the
light cone gauge if the result is available. Finally we find that D0-brane is
non-supersymmetric.
