Integrable Classical and Quantum Gravity
In these lectures we report recent work on the exact quantization of dimensionally reduced gravity [1, 2, 3, 4]. Assuming the presence of commuting Killing symmetries which effectively eliminate the dependence on all but two space-time coordinates allows us to cast the models into the form of 2d non-linear (G/H)-coset space σ-models coupled to gravity and a dilaton. This construction includes a...
متن کاملIntegrable boundary conditions for classical sine-Gordon theory
The possible boundary conditions consistent with the integrability of the classical sine-Gordon equation are studied. A boundary value problem on the half-line x ≤ 0 with local boundary condition at the origin is considered. The most general form of this boundary condition is found such that the problem be integrable. For the resulting system an infinite number of involutive integrals of motion...
متن کاملNon-perturbative Quantum Theories and Integrable Equations
I review the appearance of classical integrable systems as an effective tool for the description of nonperturbative exact results in quantum string and gauge theories. Various aspects of this relation: spectral curves, action-angle variables, Whitham deformations and associativity equations are considered separately demonstrating hidden parallels between topological 2d string theories and naive...

متن کاملThree Graded Modified Classical Yang-Baxter Equations and Integrable Systems
The 6 = 3 × 2 huge Lie algebra Ξ of all local and non local differential operators on a circle is applied to the standard Adler-Kostant-Symes (AKS) R-bracket sckeme. It is shown in particular that there exist three additional Lie structures, associated to three graded modified classical YangBaxter(GMCYB) equations. As we know from the standard case, these structures can be used to classify in a...
