M-theory giant gravitons from the perspective of type IIA superstring theory

In this paper, we study the low-energy dynamics of the giant graviton of M-theory and its 10-dimensional interpretation in type IIA superstring theory. Considering a background geometry of the form AdS7 x S4 in M-theory and assuming a giant graviton as a spherical M2-brane probe wrapping a 2-sphere and rotating along a great circle of S4, after compactifying the theory to 10 dimensions, we find that the giant is identical to a spherical D2-brane with a uniform U(1) magnetic flux on its worldvolume. Hence we find the relations between 11-dimensional quantities of a giant graviton and their 10-dimensional equivalents.
