Description
The same complex matrix model calculates both tachyon
scattering for the $c=1$ non-critical string at the self-dual radius
and certain correlation functions of half-BPS operators in $\cN=4$
super-Yang-Mills. It is dual to another complex matrix model where
the couplings of the first model are encoded in the Kontsevich-like
variables of the second. The duality between the theories is mirrored
by the duality of their Feynman diagrams. Analogously to the
Hermitian Kontsevich-Penner models, the graphs of the second model can
be written as sums over discrete points in subspaces of the
moduli space of punctured Riemann surfaces.
