From a giant M2 to a giant D2

We study the M2-brane giant graviton of M-theory from the point of view of type IIA theory. We reduce the Abelian dynamics of this giant graviton to that of a spherical D2-brane with worldvolume magnetic flux in type IIA theory. Alternatively, we describe it as a system of D0-branes expanding into a fuzzy sphere in a background with magnetic 3-form flux. The two descriptions agree in the limit of large number of D0-branes.
