We define systems of uniaxial type, which generalize Maxwell's system of equations for uniaxial crystals. We compute the geometric invariants of these systems. Using energy estimates, we prove results on the propagation of Sobolev polarization sets. The polarization sets refine the wave front sets of vector valued distributions.

We define and study the polarization sets for vector-valued distributions. Systems of real principal type are defined, and we prove that for such systems of pseudodifferential operators we have a unique propagation of the polarization sets for the solutions.

This paper studies the solvability for square systems of classical pseudodifferential operators. We assume that the system is of principal type, i.e., the principal symbol vanishes of first order on the kernel. We shall also assume that the eigenvalues of the principal symbol close to zero have constant multiplicity. We prove that local solvability for the system is equivalent to condition (ψ) on

It was a great surprise when Hans Lewy in 1957 presented a non-vanishing complex vector field that is not locally solvable. Actually, the vector field is the tangential Cauchy-Riemann operator on the boundary of a strictly pseudoconvex domain. Hörmander proved in 1960 that almost all linear partial differential equations are not locally solvable. This also has connections with the spectral instabi
