Complex marginal deformations of D3-brane geometries, their Penrose limits and giant gravitons

Spyros D. Avramis, Konstadinos Sfetsos, Dimitrios Zoakos

We apply the Lunin--Maldacena construction of gravity duals to beta-deformed gauge theories to a class of Type IIB backgrounds with U(1)^3 global symmetry, which include the multic…
