After having shown some cases in which one can apply theorems of Nota I, we give a theorem of Freedholm alternative. Then we consider solutions of the problem, having at infinity an assigned polinomial growth and prove for them a theorem of existence and uniqueness.
We give an account of existence and unicity theorems for the Dirichlet problem and of Phragmén—Lindelöf type theorems, for elliptic equations of higher order in a domain with unbounded boundary.
We give notice of an existence Theorem and prove a new unicity Theorem for the problem in the title.
We give comparison results for solutions of variational inequalities, related to general elliptic second order operators, involving solutions of symmetrized problems, using Schwarz spherical symmetrization.
