On the oscillation of first-order neutral delay differential equations with real coefficients.
A Note on Univalent Functions with Finitely many Coefficients
MSC 2010: 30C45 The main object of this article is to introduce sufficient conditions of univalency for a class of analytic functions with finitely many coefficients defined by approximate functions due to Suffridge on the unit disk of the complex plane whose image is saddle-shaped. Sandwich theorem is also discussed.
