Various geometrical structures related to the Liouville equation, are
considered. Properties of the symmetry algebra are discussed, and local
conserved currents are constructed. B\"acklund transformations for the
Liouville equation are integrated, and nontrivial generalizations of the
latter are studied, as well as the structures on them.
