Introduction,The partial differential equation.is called elliptic on a set ., provided that the principal symbol.of the operator . is invertible on . × (?. 0); . is called elliptic on ., too. This definition works for systems of equations, for classical pseudodifferential operators (.do), and for operators on a manifold Ω.
