Hidden symmetries of the AdS_{5}×S^{5} superstring
Abstract
Attempts to solve YangMills theory must eventually face the problem of analyzing the theory at intermediate values of the coupling constant. In this regime neither perturbation theory nor the gravity dual are adequate, and one must consider the full string theory in the appropriate background. We suggest that in some nontrivial cases the world sheet theory may be exactly solvable. For the GreenSchwarz superstring on AdS_{5}×S^{5} we find an infinite set of nonlocal classically conserved charges of the type that exist in integrable field theories.
