Oscillating and sign-definite solutions to autonomous functional-differential equations

T. L. Sabatulina

Perm State National Research Polytechnical University

Abstract: We consider a class of autonomous functional-differential equations for which the properties of oscillation of all solutions and positiveness of the fundamental solution are mutually complement.

Keywords: functional-differential equation, aftereffect, oscillation, sign definiteness.
