Abstract
We deduce the Toda realization of classical symmetry on two scalar fields in a geometric way, proceeding from a nonlinear realization of some associate higher-spin symmetry . The Toda equations are recognized as the constraints singling out a two-dimensional fully geodesic subspace in the initial coset space of . The proposed geometric approach can be extended to other nonlinear algebras and integrable systems.
