Description

A general expression for the symplectic structure of a higher-derivative lagrangian field theory is given. General relativity and the gravitational WZW-model are considered in this framework. In the second case we work out explicitly the Poisson bracket for both ciral solutions giving rise, in two different ways, to the classical exchange algebra of the SLq(2) group. (orig.)
