| Abstract | |
Consider A (x, D) : C-infinity(Omega, E) -> C-infinity(Omega, F) an elliptic and canceling linear differential operator of order v with smooth complex coefficients in Omega subset of R-N from a finite dimension complex vector space E to a finite dimension complex vector space F and A{*} (x, D) its adjoint. In this work we characterize the (local) continuous solvability of the partial differential equation A{*} (x, D)v = f (in the distribution sense) for a given distribution f; more precisely we show that any x(0) is an element of Omega is contained in a neighborhood U subset of Omega in which its continuous solvability is characterized by the following condition on f: for every epsilon > 0 and any compact set K subset of subset of U, there exists theta = theta(K, epsilon) > 0 such that the following holds for all smooth function phi supported in K: vertical bar f(phi)vertical bar <= theta parallel to phi parallel to W-v-1,W-1 + epsilon parallel to A(x, D)phi parallel to(L1), where W-v-1,W-1 stands for the homogenous Sobolev space of all L-1 functions whose derivatives of order v - 1 belongs to L-1 (U). This characterization implies and extends results obtained before for operators associated to elliptic complexes of vector fields (see {[}1]); we also provide local analogues, for a large range of differential operators, to global results obtained for the classical divergence operator by Bourgain and Brezis in {[}2] and by De Pauw and Pfeffer in {[}3].
