چکیده
A bstract Different frameworks exist to describe the flat-space limit of AdS/CFT, include momentum space, Mellin coordinate and partial-wave expansion. We explain origin space as smearing kernel in Poincare AdS, while latter three is global AdS. In we find a formula that unifies massless massive limit, which can be transformed Furthermore, also manage transform connecting all existed frameworks. Finally, go beyond scalar verify $$ \left\langle VV\mathcal{O}\right\rangle VV O maps photon-photon-massive amplitudes.

Near Flat Space Limit of Strings on AdS
The non-linear nature of string theory on non-trivial backgrounds related to the AdS/CFT correspondence suggests to look for simplifications. Two such simplifications proved to be useful in studying string theory. These are the pp-wave limit which describes point-like strings and the so called “near flat space” limit which connects two different sectors of string theory – pp-waves and “giant ma...
متن کاملNear-flat space limit and Einstein manifolds
We study the near-flat space limit for strings on AdS5 × M5, where the internal manifold M5 is equipped with a generic metric with U(1)3 isometry. In the bosonic sector, the limiting sigma model is similar to the one found for AdS5 × S5, as the global symmetries are reduced in the most general case. When M5 is a SasakiEinstein space like T 1,1, Y p,q and Lp,q,r, whose dual CFT’s have N = 1 supe...
متن کاملEffective Conformal Theory and the Flat-Space Limit of AdS
We develop the idea of an effective conformal theory describing the low-lying spectrum of the dilatation operator in a CFT. Such an effective theory is useful when the spectrum contains a hierarchy in the dimension of operators, and a small parameter whose role is similar to that of 1/N in a large N gauge theory. These criteria insure that there is a regime where the dilatation operator is modi...
متن کاملHolography in the Flat Space Limit Leonard Susskind
Matrix theory and the AdS/CFT correspondence provide nonperturbative holographic formulations of string theory. In both cases the finite N theories can be thought of as infrared regulated versions of flat space string theory in which removing the cutoff is equivalent to letting N go to infinity. In this paper we consider the nature of this limit. In both cases the holographic mapping becomes co...
