Solving the AdS/CFT Y-system
Solving the AdS/CFT Y-system
A bstract Using integrability and analyticity properties of the AdS 5 /CFT 4 Y-system we reduce it to a finite set of nonlinear integral equations. The $ {{\mathbb{Z}}_4} $ symmetry of the underlying coset sigma model, in its quantum version, allows for a deeper insight into the analyticity structure of …
