The HAHN-BANACH-theorem is known to have fundamental importance for several fields of mathematics. This theorem is not used concerning functionals, but operators which map into a real partially ordered vector space. In this paper is shown that the validity of this theorem is equivalent t o the vali

## Abstract Necessary and sufficient conditions for a fourth order functional differential equation of the form (1) [r(t)yβ€³(t)]β€³+f(t,y(h~1~(t)), y(h~2~(t)), …, y(h~n~(t)))=0 to be oscillatory are given when f is strongly superlinear or strongly sublinear.
