DESCRIPTION:A fine-tuning free lattice formulation of 4d N=4 S
YM\, if it exists\, would be useful for nonperturb
ative tests of the AdS/CFT correspondence. However
it is not successful so far. In this talk we poin
t out string-inspired matrix model techniques are
very useful for the nonperturbative formulation of
4d N=4 SYM. We construct a two-dimensional lattic
e with a plane wave deformation\, from which two a
dditional dimensions emerge through the Myers effe
ct. In other words we construct a D1-brane theory
from which a D3-brane theory\ncomes out. We show t
hat this formulation does not require any fine tun
ing at least to all order in perturbation theory.
If time permits\, I show some numerical results of
1d and 2d SYM theories\, in order to demonstrate
how numerical simulation works in the context of t
he AdS/CFT and the gauge/gravity duality.\n\n
