Spencer Cohomologies and Symmetry Groups,manage to unify computations by reduction to the invariant systems over a homogeneous space. The conditions of coincidence of Spencer cohomologies with the cohomologies of an invariant Spencer complex we obtain from the arithmetic of a ℂ-characteristic manifold with respect to fundamental weights of

On the Geometry of Soliton Equations,se equations may provide a better understanding of their remarkable properties. According to the geometric point of view, soliton equations are the outcome of a specific reduction process of a bi-Hamiltonian manifold. The suggestion of the paper is to pay attention also to the ‘unreduced form’ of so

Arbitrariness of the General Solution and Symmetries, symmetry reduction. We discuss the treatment of gauge systems, especially the analysis of gauge fixing conditions. As examples, the Yang-Mills equations with the Lorentz gauge and Einstein’s vacuum field equations with harmonic coordinates are considered.
