TY - JOUR T1 - Reduction of bi-Hamiltonian systems and separation of variables: an example from the Boussinesq hierarchy JF - Theor. Math. Phys. 122 (2000) 176-192 Y1 - 2000 A1 - Gregorio Falqui A1 - Franco Magri A1 - G. Tondo AB - We discuss the Boussinesq system with $t_5$ stationary, within a general framework for the analysis of stationary flows of n-Gel\\\'fand-Dickey hierarchies. We show how a careful use of its bihamiltonian structure can be used to provide a set of separation coordinates for the corresponding Hamilton--Jacobi equations.
