Let f(x,z), x∈RN, z∈CM, be a smooth function in the sense that its Fourier transform has a good behaviour. We study the composition f(x,u(x)), where u is in a generalized Hörmander Bp,k space in the sense of Björck [1]. As a consequence we obtain results of local solvability and hypoellipticity of semilinear equations of the type P(D)u+f(x,Q1(D)u,…,QM(D)u)=g, with g∈Bp,k, and fully nonlinear elliptic equations.Downloads
