A similarity principle for pascali systems
James L. Buchanan · Complex Variables Theory and Application An International Journal · 1983
It is shown that when the matrices A and B have bounded support, any solution to the Pascali system of dimension n has the representation w = SΨ where S is a nonsingular matrix continuous in the complex plane, and Ψ is a vector analytic in the domain of w. Preliminary to this a generalization of Liouville's theorem is established.
