**Langlands program** is a web of far-reaching and influential conjectures about connections between number theory and geometry. Proposed by Robert Langlands at IAS (1967, 1970), it seeks to relate Galois groups in algebraic number theory to automorphic forms and representation theory of algebraic groups over local fields and adeles.

**Geometric Langlands correspondence** is a geometric analog (aim for a reformulation) of the number theoretic Langlands correspondence.

There is a well-known relation between the **Geometric Langlands Program** and Electric-Magnetic Duality or S-duality in certain quantum field theories ---

N=4 super Yang-Mills theory in four dimensions.

More precisely, the geometric Langlands program can be described in a natural way by compactifying on a Riemann surface a twisted version of N=4 super Yang-Mills theory in four dimensions. See hep-th/0604151, Anton Kapustin, Edward Witten (2006). The key ingredients are

- the electric-magnetic duality of gauge theory,
- mirror symmetry of sigma-models,
- branes,
- Wilson and 't Hooft operators, and
- topological field theory.

Hecke eigensheaves and D-modules can be explained from the physics.

Since N=4 super Yang-Mills theory in four dimensions plays a key role in the

gauge-gravity duality

or

the AdS/CFT duality

the duality between

Type IIB string theory on AdS5 × $S^5$ space (a product of 5-dimensional AdS space with a 5-dimensional sphere); or the supergravity

and

N = 4 super Yang–Mills

on the 4-dimensional boundary of AdS5.

My question is that: So far do any researcher finds useful guidance to look at the number theory, or the

(Geometric) Langlands correspondencethrough the gravity theory (like the AdS5 space in Type IIB string theory or the supergravity)?Does the p-adic AdS/CFT have any help on this problem in math or probably not?
