This paper studies spectral properties of linear retarded functional differential equations in Hilbert spaces with the emphasis on their relations to structural operators. The equations involve unbounded operators acting on the discrete and distributed delayed terms, and the operators acting on the

## Abstract In this paper we relate the oscillation problem of the nonlinear functional differential equation (__a__(__t__)__x'__(__t__))__' + q__(__t__) __f__ (__x__(__g__(__t__)))= 0 and the nonlinear neutral functional differential equation (__a__(__t__) (__x__(__t__)__+ p__(__t__)__x__(g^\*^(__
