In the paper we investigate the role of the Newton polyhedron R,ℜ, which generates a multianisotropic Sobolev space WRpWpℜ and Gevrey space GR,Gℜ, and the role of the Newton polyhedron R(P)ℜ(P) of a polynomial P(ξ)P(ξ) ( of a linear differential operator P(D)P(D)) in the behaviour of P(ξ)P(ξ) at infinity and in the smoothness of solutions of the equation P(D)u=f.
