Nilpotent Normal Form in Dimension 4,The normal form for a vectorfield in R. with irreducible nilpotent linear part is given and we prove that it is minimal. A counting argument suffices to show that we have indeed all the terms in the normal form. The normal form is not unique.

On Operators Which Leave Invariant a Half-Space,The purpose of this talk is to give a geometric characterization of those linear continuous operators A:D(A) E→E (D(A) dense in E), where E is a real locally convex topological vector space, whose adjoint A*:D(A*) E*→E* (E* the dual space of E) has a nonnegative real eigenvalue.
