TOPIC: Exactly solvable 1+1 dimensional QFT's in finite volume

Abstract
I will explain a new method of solution of 1+1 dimensional quantum field theories based on the integrable classical discrete Hirota dynamics. The main examples will be the relativistic O(4) sigma model, as well as the superstirng sigma model whose solution allowed recently, due to the so called AdS/CFT correspondence, the exact calculation of spectrum of anomalous dimensions in 4-dimensional Yang-Mills theory with N=4 supersymmetries.
