Query: Brane Geometry and Dimer Models   The field content and interactions of almost all known gauge theories in
AdS_5/CFT_4 can be expressed in terms of dimer models or bipartite graphs drawn
on a torus. Associated with the fundamental cell is a complex structure
parameter tau_R. Based on the brane realization of these theories, we can
specify a special Lagrangian (SLag) torus fibration that is the natural
candidate to be identified as the torus on which the dimer lives. Using the
metrics known in the literature, we compute the complex structure tau_G of this
torus. For the theories on C^3 and the conifold and for orbifolds thereof tau_R
= tau_G. However, for more complicated examples, we show that the two complex
structures cannot be equal and yet, remarkably, differ only by a few percent.
We leave the explanation for this extraordinary proximity as an open challenge.
