Abstract:
We formulate an algebraic definition of Gardner's deformations for completely
integrable bi-Hamiltonian evolutionary systems. The proposed approach extends
the class of deformable equations and yields new integrable evolutionary and
hyperbolic Liouville-type systems. We find an exactly solvable two-component
extension of the Liouville equation.
