Query: Giant Hedge-Hogs: Spikes on Giant Gravitons   We consider giant gravitons on the maximally supersymmetric plane-wave
background of type IIB string theory. Fixing the light-cone gauge, we work out
the low energy effective light-cone Hamiltonian of the three-sphere giant
graviton. At first order, this is a U(1) gauge theory on R x S^3. We place
sources in this effective gauge theory. Although non-vanishing net electric
charge configurations are disallowed by Gauss' law, electric dipoles can be
formed. From the string theory point of view these dipoles can be understood as
open strings piercing the three-sphere, generalizing the usual BIons to the
giant gravitons, BIGGons. Our results can be used to give a two dimensional
(worldsheet) description of giant gravitons, similar to Polchinski's
description for the usual D-branes, in agreement with the discussions of
hep-th/0204196.
